RESULTS OF ABS ANALYSIS


It is important to note that the data tables and results presented here are experimental shipping container numbers, and therefore subject to change due to further research and analysis.

The ABS analysis identified that:

• While statistics for a relatively large proportion of Tariff Classification Numbers might potentially enable the identification of an organisation and need to be confidentialised, these classifications represented a very small proportion of container movements (table 3)
• Limiting information to the top 10 delivery postcodes for each port provides some useful information but is unlikely to be sufficient for the needs of all stakeholders

Table 3 shows that applying a simple but conservative confidentiality method, at the 8 digit TCN level, resulted in restrictions being applied on average to 24.5% of non-nil commodities but to only 1.3% of total TEUs. The percentage restricted is less at the broader levels of the classification.

TARIFF CLASSIFICATION NUMBER (TCN) AT SIX DIGIT CODE LEVEL, low range cell values

An alternative method for minimising the possibility of releasing information that may enable the identification of an individual business is to suppress low value cells (table 4). In this study all cells with less than 5 TEU were identified. Before other necessary confidentiality restrictions were applied, the cell loss with this approach was approximately 40% of cells per month. This technique impacted on a fairly low proportion of TEU at approximately 2% per month. This method was rejected due to this high loss of cells.

AUSTRALIAN SEAPORTS AND CONTAINER DELIVERY POSTCODES

The distribution of containers from Australia’s five major seaports to delivery postcodes was investigated. The ports selected were Sydney, Melbourne, Brisbane, Adelaide and Fremantle.

Table 5 shows the top 10 postcodes for each of these five ports along with a ratio of the TEUs for each postcode to the combined TEU for the top 10 postcodes, and the total TEUs for that port. The table shows that for each of the five ports the delivery postcode with the highest TEU ranged between around one fifth and just under one third of the total for each port’s top 10 postcodes.

For Sydney the delivery postcode of 2164 (which includes the suburbs of Smithfield, Wetherill Park and Woodpark) received 20% of all containers sent to the top 10 postcodes and 7% of all containers sent from the port. For Melbourne the delivery postcode of 3175 (which includes Dandenong, Bangholme and Dunearn) received 21% of all containers sent to the top 10 postcodes and 9% of all containers sent from the port. For the port of Brisbane the delivery postcode of 4178 (which includes the localities of Port of Brisbane, Wynnum and Lytton) received 18% of all containers sent to the top 10 postcodes and 9% of all containers sent from the port.

For Adelaide the delivery postcode of 5013 (which includes the suburbs of Rosewater, Gillman and Ottaway) received 30% of all containers sent to the top 10 postcodes, and 15% of all containers sent from the port. For the port of Fremantle the delivery postcode which received 19% of all containers sent to the top 10 postcodes, and 11% of all containers sent from the port, was 6106, which includes Welshpool, Kewdale, Cloverdale and Perth Airport.

The TEU of the top 10 delivery postcodes accounted for 61% of total port TEU for Fremantle. Brisbane recorded 51%, Adelaide recorded 49%, Melbourne (41%) and Sydney (37%).

This analysis indicates that statistics on the top 10 delivery postcodes for each port provides some very useful information but is unlikely to be sufficient for the needs of all stakeholders.

Maps presented later in this paper illustrate how these delivery postcodes align with container storage depot, handling and dispatch facilities for each of the five ports.

CONTAINER DELIVERY POSTCODES, Ports, aggregated to State & Territory

Delivery postcodes aggregated to State and Territory level for TEU totals for each of the five ports examined showed (not surprisingly) that the bulk of TEU for each port delivered within the state where the port was located (table 6). Around 90% of TEU was delivered to postcodes in each port’s respective state, ranging from a low of 88% for Victoria from the port of Melbourne, to a high of 92% for both Western Australia from the port of Fremantle and Queensland from the port of Brisbane. Both the state of South Australia and the combined state and territory of New South Wales and the Australian Capital Territory recorded 90% of Adelaide’s and Sydney’s TEU.

Around 10% of TEU discharged at a port were distributed to other states and territories. For example, 6% of containers discharged at Sydney went to Queensland and 3% to Victoria, while for the port of Melbourne 5% of TEU went to South Australia, and 5% of Brisbane TEU went to the combined New South Wales and the Australian Capital Territory.

While only 5% of TEUs discharged at Melbourne (42,166 out of 826,025) were sent to South Australia, this compares to the total TEU of 60,942 discharged direct to the port of Adelaide.
