The Australian Bureau of Statistics released a feature article entitled "Are we building on smaller blocks?" The overall answer is an unsurprising yes, within which in the last couple of years the average site area has increased modestly from a trough reached at the beginning of the decade. In 1993-94 the average site area of new houses in Australian capital cities was 802sqm. This compares to 735sqm in 2003-04 and a low of 702sqm in 1999-00. Hence over the last four years the average site area has ticked up moderately, but looks to have stabilised at around the 735sqm mark, still some 67sqm smaller than 11 years previously. The decline in average site area has been quite noticeable for most growth Statistical Local Areas (SLA's). For example, in Melton - East, Melbourne, the average block size of a new house has fallen from 716sqm in 1994-95 to 571sqm in 2003-04; the average block size of a new house in Bankstown, Sydney, has fallen from 667sqm in 1998-99 to 614sqm in 2003-04. A minority of SLA's have bucked the trend. Tea Tree Gully - North in Adelaide has seen an increase in average block size from 596sqm in 199394 to 735sqm in 2003-04. Swan, in Perth, had an increase from 710sqm in 1994-95 to 814sqm in 2003-04. In aggregate terms the only capital city where average block size has increased is Brisbane. The site area of new houses in the Brisbane Statistical Division increased from 923sqm in 1993-94 to 964sqm in 2003-04, substantially above the national average for Australian capital cities.
