The most serious offence is defined as the offence for which prisoners have received the longest sentence. Nearly half (45%) of all sentenced prisoners were convicted of offences involving violence or the threat of violence, including homicide (10%), sexual assault (10%), assault (11%) and robbery (14%) (table 11.29). Another 12% were in prison for unlawful entry with intent, while a further 10% were serving sentences for illicit drug offences.

(b) A majority of full-time prisoners sentenced in the ACT are held in NSW prisons.

There were differences in the types of offences for which men and women were imprisoned. Graph 11.30 shows that the highest numbers of offences for males in prison at 30 June 2001 were robbery (14%), UEWI (12%), assault (11%) and sexual assault (11%). In the case of female prisoners, drug offences (14%), theft and related offences (14%), robbery (12%) and homicide (11%) were the most frequent reasons for imprisonment.

Aggregate length of sentence is a measure of the sentences imposed on an offender, sometimes taking multiple offences into account. It is not measured for prisoners who receive an indeterminate type of sentence such as 'life', and periodic detainees' sentences are measured separately. At 30 June 2001 the average aggregate sentence of all prisoners sentenced to a specific term was 4.8 years. Male prisoners were serving an average aggregate sentence of 4.9 years, compared to an average of 3.3 years for female prisoners.

Prisoners serving sentences of at least one year but less than five years accounted for the highest proportion of prisoners in all states and the Northern Territory (table 11.31). Prisoners with indeterminate (including 'life') sentences made up 5% of all prisoners.

(b) The aggregate sentence is the longest period that the offender may be detained under sentence in the current episode. Charges pending which are likely to extend the current episode are ignored.
(c) Prisoners sentenced to full-time custody in the ACT are held in NSW prisons and are included in the NSW figures.
(d) Indeterminate prisoners includes those sentenced to life imprisonment, those held at the Governor's pleasure and those subject to ministerial or administrative decisions.

Younger prisoners were more likely to be serving shorter sentences than older prisoners. While 1% of prisoners aged less than 20 years were serving a sentence of 10 years and over (excluding Indeterminate sentence lengths), this proportion progressively increased across the age groups to be 23% for prisoners aged 50 years and over (table 11.32).
