This is important because weaker buyer demand - driven by both the post-Budget changes and higher interest rates - does not necessarily lead to a sustained build-up in properties for sale. Housing supply is highly responsive to market conditions. Unless an owner needs to sell, they can delay putting their property on the market when prices are weaker or buyers become more cautious. When enough sellers make that decision, the reduction in new supply starts to offset weaker demand.
That appears to be happening in Sydney and Melbourne. Fewer properties are coming onto the market, while the stock already available for sale continues to be absorbed. The result is a progressively tighter balance between buyers and sellers than might otherwise have occurred following the Budget.
The contrast with Brisbane and Perth is striking. New listings have also declined in both markets, falling 2.7 per cent in Brisbane and 10.5 per cent in Perth since May. But active listings have moved sharply in the opposite direction, rising 27.5 per cent in Brisbane and 20.2 per cent in Perth. Fewer homes are being newly listed, yet more properties are sitting on the market.
That suggests the issue in Brisbane and Perth is not a rush of owners deciding to sell. Instead, existing stock is taking longer to clear. Adelaide is showing a similar, although less pronounced, pattern: new listings have risen only 2.4 per cent since May, while active listings are up 15.0 per cent.
The post-Budget housing market is therefore becoming increasingly divided. Sydney and Melbourne experienced some of the earliest and largest weakness, but sellers are now responding by withdrawing supply. In Brisbane and Perth, where conditions remained stronger for longer, stock is instead accumulating despite fewer new properties coming onto the market.
For Sydney and Melbourne, that seller pullback provides an important buffer against further weakness, but the outlook remains fragile. A further interest rate rise would reduce borrowing capacity and weaken buyer demand again. For now, however, buyers are also being presented with fewer properties to choose from. After leading the initial downturn, Australia’s two largest housing markets are moving into a very different phase.
