Cap is $800,000 SOUTH of the 26th parallel (which includes all of metropolitan Perth) and $1,000,000 NORTH of it. We store the southern figure because that is where almost every buyer is; the northern cap is higher, so the stored value never overstates eligibility. The southern cap rose from $750,000 on 7 May 2026 in the 2026-27 Housing Taxation Package.
