Australian Taxation Office Taxation Statistics 2023–24, individuals Table 25. Figures describe taxpayers who live in postcode 6714 — not a suburb-level official statistic. Rental investment is the share of local taxpayers reporting rental income or loss, not the share of local properties owned by investors.
Percentiles rank this postcode among unique postcodes in WA, so suburbs that share a postcode are not counted twice. Dollar figures are compared with Australia-wide ATO medians from the same release. Median net rent is among taxpayers who reported the rent label and can be negative.
