This paper provides a concordance of postcodes to Commonwealth
electoral divisions, based on the results of the 2001 Census. It is
an update of Research Paper No. 12, 2000‑01, and reflects changes
to electoral boundaries brought about by recent electoral redistributions.
The concordance will enable senators and members to convert information
published by postcode by organisations such as Centrelink or the Australian
Taxation Office into electoral division totals. For example, the electoral
division of Gorton consists of postcodes 3022, 3023,
3036, 3037 and 3038 plus parts of postcodes 3020, 3021 and 3335.
The information is shown in two parts, electoral divisions
by postcode and postcodes by electoral division. Where a postcode boundary
was found to cross electoral division boundaries, a percentage was calculated
to show the proportion of the total postcode population that is located
in each electoral division.
This information was generated by processing the Census
2001 total population figures in each Census Collection District (CCD)
and allocating it to the relevant postcode and the relevant electoral
division. It should be noted the boundaries for the electoral divisions
and the postcodes are what the Australian Bureau of Statistics refers
to as Census derived boundaries, that is boundaries made up by fitting CCDs as closely
as possible to the true electoral division and postcode boundaries.
This derivation system means that some small postcodes which make up
only a part of a CCD are not listed in the Census. To compensate for
this, a list of these missing postcodes has been generated and the postcodes
allocated to electoral divisions using a map overlay method. Nevertheless,
some non-residential postcodes (for example Post Office Box type) are
still missing from this concordance.
The information in this paper refers to the electoral
divisions as they will be at the next election, that
is following the 2002 redistribution in Victoria
and the 2003 redistributions in Queensland
and South Australia.
