Federal Defendants, Australia methodology

Latest release
Reference period
2022-23 financial year

Overview

Scope

Defendants (persons or organisations) charged against Commonwealth legislation with a case finalised in criminal courts during the financial year 2022–23. Each case separately finalised is counted, excluding court level transfers (unless specified).

Geography

Data are available for states and territories, and Australia.

Source

Administrative data supplied to the ABS by courts administration agencies or statistical agencies in each state and territory.

Collection method

Administrative data for all finalised criminal court federal defendants in the Higher (Supreme and District/County courts) Magistrates’ and Children’s Courts, are collected annually at the completion of each financial year. 

History of changes

  • An updated Sentence Type Classification was introduced for the first time in 2022–23. This has been applied at a broad level to earlier years (where possible), and any issues in consistency over time have been noted. 

Data collection

Scope and Coverage

The Federal Defendants, Australia, 2022–23 data relates to persons and organisations charged with an offence against Commonwealth legislation, whose case(s) have been finalised within the criminal jurisdictions of the Higher (Supreme and District/County Courts), Magistrates' or Children's courts between 1 July 2022 and 30 June 2023.  Information is presented about the offences, outcomes and sentences associated with these defendants. 

Defendants whose cases relate only to offences under state or territory legislation are not in scope of this release, but are included in Criminal Courts, Australia.

Charges against Commonwealth legislation can be prosecuted by:

  • State and territory police agencies
  • The Australian Federal Police
  • The Commonwealth Director of Public Prosecutions
  • State Directors of Public Prosecutions
  • The Australian Securities and Investments Commission
  • The Australian Tax Office
  • Other (generally Commonwealth) authorities

The following are excluded from the scope of the Federal defendants collection:

  • Federal offences based on national laws enacted under state and territory legislation (excluded from 2016–17 onwards)
  • the Australian Road Rules and associated state and territory enacting legislation

Defendants finalised on Cocos (Keeling) Islands and Christmas Island are included in the counts for Western Australia, where applicable. Defendants finalised in Jervis Bay Territory and Norfolk Island are not included.

Data Source

Statistics presented in this publication are based on administrative unit record data supplied to the ABS by the agencies responsible for courts administration in each state and territory, except for Queensland (where data are supplied via the Office of the Government Statistician), and New South Wales (where data are supplied via the Bureau of Crime Statistics and Research).

To ensure consistency between the states and territories, each one is required to provide data coded to national classifications and standards. For more information see classifications under ‘Data release’.

Data processing

Counting methodology

The counting unit for this collection is the finalised defendant of a federal offence.

A finalised defendant is defined as a person or organisation for whom all charges within a case have been formally completed so that they cease to be an active item of work for the court during the reference period. Federal offences are charges against Commonwealth legislation.

The Federal Defendants collection does not count unique persons, instead the following counting rules are applied:

  • Where a defendant is finalised for more than one case, on the same date and in the same court level, their records are merged, and they are counted as one finalised defendant
  • Where a defendant is finalised for more than one case, on separate dates within the reference period, they will be counted once for each date they were finalised
  • Where a defendant is finalised in the Magistrates' Courts whilst other charges are committed to, and finalised in the Higher Courts, they will be counted once for each court level they were finalised in during the reference period

Transfers

The following counting rules apply with regards to defendants transferred from, or between court levels:

  • Defendants transferred from one Higher Court level to another Higher Court level (for example from a County Court to Supreme Court) are considered as finalised only once (from the level they finally left)
  • Defendants transferred from a Magistrates' or Children’s Court to a Higher Court (or vice versa) are considered as finalised twice (once in each of the courts)
  • Defendants transferred from the Magistrates' or Children's Courts to Specialist Courts for finalisation (e.g. Drug Courts, Indigenous Courts) are considered finalised (by transfer) in the criminal court that initiated the transfer. Defendants may then, upon completion of the program, return to the court that requested the transfer, for an additional finalisation

From 2019–20 onwards, transfers are excluded from defendant counts in some tables to remove the double-counting of defendants who were transferred and subsequently adjudicated in a different court level. Excluding transfers enables a more accurate representation of defendant characteristics, particularly for more serious offences where transfers to a Higher Court are more common.

Data Items

Defendants who were finalised for more than one offence will have counting rules applied to determine their principal method of finalisation, offence, sentence type and other characteristics for inclusion in data tables.

Age

The age presented in the Federal Defendants data refers to the age (in years) of defendants at the time of case finalisation. It is not the age at which the defendant committed the offence.

Sex

The categories used for defendant sex are male, female, organisations, other, and unknown. The number of defendants in the category of ‘other’ is currently not published due to small numbers and inconsistent use, though these defendants are included within the total.

Court levels

Data are reported at three court levels: Higher Courts, Magistrates’ Courts and Children’s Courts.

In this publication, the Higher Courts comprises the Supreme and Intermediate Courts. All states and territories have a Supreme Court that deals with the most serious criminal matters, generally referred to as an indictable offence (such as serious sexual offences or drug trafficking). The larger states (New South Wales, Victoria, Queensland, South Australia and Western Australia) also have an intermediate level of court, known as the District Court or County Court, which deal with most serious offences. All defendants that are dealt with by the Higher Courts have an automatic entitlement to a trial before a judge and jury. In some states and territories, the defendant may elect to have their matter(s) heard before a judge alone. Children treated as adults by the court may be included in the Higher Courts defendant counts.

The lowest level of Criminal Court is the Magistrates’ Court (also known as the Court of Summary Jurisdiction, Local Court or Court of Petty Sessions) which hears most criminal cases. Cases heard in the Magistrates’ Courts do not involve a jury – rather, a magistrate determines whether the defendant is guilty or not guilty. Children treated as adults by the courts may also be finalised in the Magistrates' or Higher Courts.

Each state and territory has Children's Courts to deal with offences alleged to have been committed by a child. These courts mainly hear summary proceedings but do have the power to hear indictable matters in some states and territories. 

Defendants are considered to be a child where they are under 18 years of age at the time they committed an offence. Prior to February 2018, defendants in Queensland were considered to be a child by the courts where they were aged under 17 years.

A person can only be charged with a criminal offence where they are aged 10 years or over. Most states are currently reviewing the minimum age of criminal responsibility, with a rise in age expected. The Northern Territory and the Australian Capital Territory lifted the minimum age to 12 years (in August and November 2023 respectively) which is after the reference period of this release and data is unaffected. 

Principal federal offence

Principal offence refers to the most serious offence (based on ANZSOC) associated with a finalised defendant. For defendants finalised with a single offence type, this is their principal offence.

For defendants with multiple offence charges finalised at the same time, the following are used to assign a principal federal offence:

For 2017–18 and prior years, the principal federal offence is based on the method of finalisation and NOI only. The 2020–21 publication introduced sentence type and length/amount to the principal federal offence allocation rule, for data from 2018–19 onwards. The new derivation applies to both the ANZSOC principal offence, and the principal federal offence group.

Where a defendant has multiple charges, their principal federal offence is determined using a multi-step process. The first is to code the outcome for each offence to a method of finalisation group, which is then ranked as follows:

  • Defendant deceased, unfit to plead, or not guilty by reason of mental illness
  • Charges with guilty outcome
  • Charges not proven
  • Transfer of charges to other court levels
  • Charges withdrawn
  • Other non-adjudicated finalisation
  • Unknown/not stated

The charge with the highest ranked method of finalisation group is allocated as the principal federal offence.

If there are multiple charges with the same method of finalisation group, the offence with the most serious sentence (based on the Sentence type classification) is allocated as the principal federal offence. If multiple charges received the same sentence type, the offence with the greatest sentence length/amount is allocated as the principal federal offence.

The NOI, which ranks offences according to perceived seriousness, is used to select the principal federal offence where there are multiple charges and they have the same method of finalisation group, sentence type and sentence length/amount.

For example, for a federal defendant with guilty outcomes for assault receiving a three-month sentence to custody in a correctional institution, and import of illicit drugs receiving a nine-month sentence to custody in a correctional institution, their principal offence would be import of illicit drugs. This is different from the methodology previously used, where the principal offence would be assault. Any charges for the same defendant withdrawn or not proven would not be considered.

Method of finalisation

Method of finalisation refers to how a charge is concluded by a criminal court. For defendants who had multiple charges with varying outcomes, the method of finalisation is assigned based on the following order of precedence:

  • Defendant deceased
  • Unfit to plead
  • Not guilty by reason of mental illness/condition
  • Guilty finding by court
  • Guilty outcome n.f.d.
  • Guilty plea by defendant
  • Guilty ex parte (Magistrates’ Courts and Children’s Court only)
  • Acquitted by court
  • Guilty outcome n.f.d.
  • No case to answer at committal (Magistrates’ Courts and Children’s Court only)
  • Charge unproven n.e.c.
  • Committed for trial (Magistrates’ Courts and Children’s Court only)
  • Committed for sentence
  • Transfer between court levels
  • Transfer to non-court agency
  • Withdrawn by the prosecution
  • Other non-adjudicated finalisation n.e.c.
  • Unknown/not stated

Principal federal sentence

Federal defendants with more than one sentence type (for either a single offence or multiple offences) are assigned a principal sentence, which is intended to reflect the most serious sentence based on the hierarchy of the Sentence type classification. For ease of reading, the term is abbreviated to principal sentence throughout this publication.

Defendants can receive:

  • A single sentence for a single offence with a guilty outcome
  • A single sentence for multiple offences with a guilty outcome
  • Multiple sentences for a single offence with a guilty outcome
  • Multiple sentences for multiple offences with a guilty outcome

Compound (or ‘complex’) sentences can be broadly defined as sentences, served in the community, that include various components or conditions, such as program attendance, community work, drug or alcohol treatment, counselling and education. These sentences are becoming increasingly common across states and territories due to their flexibility, with judges/magistrates able to tailor a sentence to suit the circumstances of an offender and their offending, whilst providing for both restitution and rehabilitation.

The Sentence type classification 2023 has been designed to reflect the severity of compound sentences, and improve comparability of sentences within and across states and territories. This is done by taking into consideration the components or conditions imposed within each compound sentence when coding to the classification, so that sentences of a similar nature and level of severity are categorised together. 

Data for the 2022–23 cycle was collected according to this approach, and historical data for the years prior were also mapped to the new classification. The application of the new classification has, for several jurisdictions, resulted in changes of the treatment of some sentence orders, see Data comparability – State and territory notes for more detail. 

Duration

Duration is a measure of court timeliness, representing the time taken (in days) between the date a defendant’s case(s) was initiated in court (through committal or registration) and the date they ceased to be an item of work for the court as follows:

Duration = Date of finalisation – Date of initiation + 1

Revisions

An updated Sentence Type Classification was introduced for the first time in 2022–23 data. This has been backcast at a broad level to principal sentences in earlier years (where possible), and any issues in consistency over time have been footnoted.

Some offences previously assigned to 05 Communications group have now been assigned to 02 Child sexual abuse offences. For the 2022–23 release, data for these federal offence groups have been revised from 2020–21.

Data release

Classifications

Classifications provide a framework for organising and presenting data in a comparable and consistent manner. The key classifications used for this collection are:

ANZSOC

Offence data are presented according to the Australian and New Zealand Standard Offence Classification (ANZSOC), 2011.

For ease of reading, some ANZSOC offence names have been abbreviated throughout this publication as follows:

  • Dangerous or negligent acts endangering persons appear as 'Dangerous/negligent acts'
  • Abduction, harassment and other offences against the person appear as 'Abduction/harassment'
  • Robbery, extortion and related offences appear as ‘Robbery/extortion’
  • Unlawful entry with intent/burglary, break and enter appear as 'Unlawful entry with intent'
  • Theft and related offences appear as ‘Theft’
  • Fraud, deception and related offences appear as ‘Fraud/deception’
  • Prohibited and regulated weapons and explosives offences appear as 'Weapons/explosives'
  • Offences against justice procedures, government security and government operations appear as 'Offences against justice'
  • Child pornography is also referred to as child abuse material offences.

Principal federal offence groups

The Federal offence groups presented in this collection provide an alternate way (to the ANZSOC) of grouping federal offences, based on offence types that are of particular interest to users of federal defendants data.

The federal offence groups are not a formal ABS standard nor related to ANZSOC, and may comprise offences that reside in different ANZSOC divisions. For the definitions of groups and the Commonwealth Acts, sections and ANZSOC categories contained within each group refer to the Federal offence groups.

The federal offence groups presented are largely based on the Commonwealth Act the defendant was charged under, with the exception of offences against the Criminal Code Act 1995, Crimes Act 1914, Migration Act 1958, Competition and Consumer Act 2010 and Corporations (Aboriginal and Torres Strait Islander) Act 2006 which are assigned using both Act and Section level information. The groups are subject to regular review, following changes to federal legislation or emerging user needs.

A principal federal offence group is assigned by selecting a defendant’s principal offence (as outlined in Principal federal offence) and then using the underlying legislation to select the corresponding federal offence group. For a small number of defendants, where there is more than one federal offence group associated with the defendant's highest ranking ANZSOC offence, the following secondary hierarchy (of federal offence categories) is applied to select the principal federal offence group:

  • Human trafficking, slavery and sexual offences
  • Child sexual abuse offences
  • Drugs
  • Terrorism
  • International
  • Commonwealth officials
  • Justice offences
  • Social Security
  • Fraud
  • Migration offences
  • Defence
  • Proceeds of Crime
  • Illegal Fishing
  • Financial
  • Import/Export Offences
  • Communications
  • Maritime
  • Environmental
  • People Smuggling
  • Tax
  • Security
  • Commonwealth property
  • Transport
  • Aviation
  • Other
  • Illegal use/importation of weapons

From 2021–22, the offences included in the category ‘Terrorism’ have been expanded to include international terrorism or foreign incursion offences, advocating for terrorism, offences relating to control or preventative detention orders, and failure to provide information relating to terrorist acts which are either new offences or were previously coded to federal offence groups of ‘Security’, ‘Justice’, or ‘International’. For more information on the Acts included refer to the Federal offence groups.

Prior to 2019–20, the category 'Commonwealth sexual offences' included sexual offences against a minor. These offences have since been included in the new ‘Child sexual abuse offences’ category, which is an expansion and re-labelling of the previous ‘Child sexual exploitation offences’ category. Subsequently, in 2021-22, the federal offence category ‘Commonwealth sexual offences’ was relabelled ‘Human trafficking, slavery and sexual offences’ to better reflect the remaining content.

Method of finalisation

Method of finalisation refers to how a criminal charge is concluded by a criminal court.  The Method of Finalisation Classification contains the main categories of:

  • Adjudicated finalisation – a judgement or decision by the court as to whether or not the defendant is guilty of the charge(s) against them
  • Non-adjudicated finalisation – a charge(s) considered to have been completed even though a judgement has not been handed down by the court (e.g. withdrawn by the prosecution, defendant deceased, unfit to plead, or transfers to non-court agencies)
  • Transfers to other court levels – a court order for the criminal charge(s) to be transferred to another court level for adjudication or sentencing

Sentence type

The Sentence Type Classification 2023 describes the types of sentences that are handed down by the court for offences with a guilty outcome, and includes the main categories of:

  • Custody in a correctional institution
  • Intensive penalty in the community
  • Fully suspended sentence of imprisonment
  • Community service/work
  • Moderate penalty in the community
  • Monetary orders (largely fines)
  • Good behaviour (incl. bonds)
  • Nominal and other penalties

The previous Sentence Type Classification was used for releases prior to 2022–23. However, earlier data has been transitioned to the new classification structure where possible, to provide time series comparability. 

In some cases, defendants with a method of finalisation of 'not guilty by reason of mental illness/condition' may have a type of order imposed. However, these sentences are not included in this collection.

Confidentiality

The Census and Statistics Act 1905 provides the authority for the ABS to collect statistical information, and requires that statistical output shall not be published or disseminated in a manner that is likely to enable the identification of a particular person or organisation. To minimise the risk of identifying individuals in aggregate statistics, perturbation has been applied to all data presented in this publication, to randomly adjust cell values and summary variables. This technique involves small, random adjustment of the statistics and is considered the most satisfactory technique for avoiding the release of identifiable statistics while maximising the range of information that can be released. These adjustments have a negligible impact on the underlying pattern of the statistics.

The result of perturbation is that a given published cell value will be consistent across all tables, but the sum of the components of a total will not necessarily be the same as the published total, in some tables. As such, proportions may add to more or less than 100%. Readers are advised to use the published totals rather than deriving totals based on the component cells. Cells with small values may be proportionally more affected by perturbation than large values. Users are advised against conducting analyses and drawing conclusions based on small values.

Data comparability

National comparability

National standards and classifications are used in this collection to produce nationally comparable data. However, various factors can impact data quality and comparability, including:

  • Challenges with meeting national standards due to courts data systems being designed for the purpose of administration of court business (as opposed to national statistical purposes)
  • Modification over time to data systems and methodology used to extract/compile data
  • Refinements to data quality procedures
  • Legislative or operational differences across states and territories (e.g. differences in the types of matters able to be heard, and the sentencing options available to the courts).

The Federal Defendants collection presents a subset of all defendants finalised in Australia's criminal courts, as published in Criminal Courts, Australia. However, a federal defendant may also be finalised for state or territory offences in the same reference period, so the difference between all defendants and federal defendants does not equal the count of defendants with state/territory offences.

The data in this publication may not be comparable to data published in other national and state/territory publications due to differing scope and counting rules.

State and Territory comparability

The following information highlights events or processes unique to a state or territory that may have impacted on the data for the Federal Defendants collection. Where a state or territory is not listed below, there are no specific notes for that state or territory for this release. For other issues specific to a state or territory that have impacted on the Criminal Courts collection more generally, refer to ‘State and territory specific information’ in the Methodology of Criminal Courts, Australia.

An updated Sentence Type Classification was introduced in the 2022–23 release. While principal sentence results from previous years were broadly mapped to the new categories, full backcasting was not possible due to the extra detail which would be required. Further, there were changes in sentence coding for 2022–23 which also contributed to movements in the Principal Sentence data as noted in the applicable state and territory notes below. 

New South Wales

With the introduction of the new Sentence Type Classification, from 2022–23 fully suspended sentences with supervision under Commonwealth legislation are coded to Intensive custody in the community. In addition, some community orders including Good behaviour orders with conditions are now coded to Moderate penalty in the community where appropriate.

Queensland

From 2021–22 there has been a change in the reporting of sentences that include both a term of imprisonment and a Good Behaviour Order (GBO). In previous years this sentence combination has been reported as GBO only, and this has been amended to also report the term of imprisonment. The change resulted in an increase in custody in a correctional institution and a decrease in Good behaviour bond/recognisance order in Queensland in 2021–22. Caution should be used when comparing with data prior to 2021–22.

Western Australia

Between 2012–13 and 2021–22, intensive supervision orders (both adult and juvenile) were coded as community service or a moderate penalty in the community. However, from 2022–23 the new Sentence Type Classification better reflects the nature and severity of the conditions imposed, resulting in an increase in defendants sentenced to an intensive penalty in the community, and associated decrease in community service and moderate penalty in the community.

Australian Capital Territory

The Australian Capital Territory (ACT) historically had a high proportion of defendants with a principal federal offence of Traffic and vehicle regulatory offences compared with most other states and territories. This was due to parking offences being lodged under Commonwealth legislation specific to the Australian National University. From 2019–20 a significant amount of these offences were lodged under the ACT Road Transport (Road Rules) Regulation which is outside the scope of the Federal Defendants collection, resulting in a decrease in the number of federal defendants in the ACT. 

Federal defendants in the ACT are also over-represented in Public order offences, which mostly relates to offences of trespassing on Commonwealth property.
