Land Supply

In reply to the Hon. J.A. DARLEY (22 September 2021).

The Hon. R.I. LUCAS (Treasurer): The Attorney-General has advised:

1. In June 2021, the Attorney-General’s Department (the department) published the Land Supply Report for Greater Adelaide (the report). This report analyses population growth and urban development trends, and provides a detailed summary of greenfield, urban infill and employment land supply for each region. The report is a part of an overall program for managing growth and development in South Australia.

In relation to greenfield land supply, I can advise the following:

For the Greater Adelaide region, the report identifies that there is a sufficient supply of zoned residential greenfield land to accommodate projected population growth under medium and high scenarios for at least the next 10 years.

At the subregional level, the report recognises that greenfield land is unevenly distributed with abundant supply in northern Adelaide, limited supply in southern Adelaide and significant supply in the Adelaide Hills (namely in Mount Barker).

The report identifies that a high population growth scenario would see increased pressure on zoned greenfield land supply within the outer south region (the City of Onkaparinga council area) in the next five years, unless additional land is rezoned.

As a part of the new Planning and Design Code, the department is in ongoing discussions with landowners regarding opportunities to rezone land for residential development through the code amendment process. Urban infill land supply is made up of general infill (small-scale) and strategic infill (large-scale) developments across the established urban area:

General infill development accounted for 37 per cent of the net dwelling increase across Greater Adelaide over the past 10 years, while strategic infill contributed 30 per cent.

The report identifies that there is sufficient capacity within Greater Adelaide’s established urban areas to accommodate projected demand for general infill (small-scale) based on current policy settings in the P&D code.

The supply from strategic infill development sites (i.e. Lightsview, Bowden, AAMI, CBD and urban corridors) is currently adequate. However, future supply is more reactive to market conditions. For example, the supply of apartments coming from the Adelaide CBD has slowed considerably since the COVID pandemic in early 2020.

2. The Valuer-General has provided the following data as at 30 June 2021 which outlines the average capital value (as at 1 January 2021) of residential vacant land within the requested areas.

There were an estimated 12,632 vacant residential allotments within Greater Adelaide. These allotments are deposited and do not include allotments currently under assessment. Vacant lots recorded comprise an estimated:

2,793 vacant residential allotments within the southern regions of Adelaide (including the City of Onkaparinga) with an average capital value of $313,428;

5,390 vacant residential allotments within the northern regions of Adelaide (including Playford, Gawler, and parts of Light and Adelaide Plains council areas) with an average capital value of $200,054;

3,122 vacant residential allotments within the eastern regions of Adelaide (Adelaide Hills areas) with an average capital value of $343,758; and

1,327 vacant residential allotments within the western regions of Adelaide with an average capital value of $389,609.
