Outlook and Official Responses

The Treasury’s housing task force warned that prolonged auction weakness could erode construction employment by up to 4%. The Australian Prudential Regulation Authority (APRA) signaled a possible review of loan‑to‑value ratios for high‑risk borrowers. Industry groups advise sellers to consider off‑market negotiations and to price aggressively to attract the limited pool of qualified buyers.

Frequently Asked Questions

Why are auction numbers falling so sharply?

Credit tightening and higher borrowing costs have reduced buyer financing capacity, causing many sellers to postpone or cancel auctions.

What does a sub‑$100k suburb mean for first‑time buyers?

It offers entry‑level affordability but often comes with limited local services and lower rental yields, so buyers should conduct thorough due‑diligence.

How are regulators responding to the housing market plunge?

APRA is reviewing loan‑to‑value guidelines, while the Treasury is preparing targeted stimulus for regional construction to stabilize employment.
