Perth (Non-Adf Housing) housing and COLA at a glance
Perth (Non-Adf Housing), Australia (DoD locality AU025).
An E-5 with dependents can rent up to $2,135 a month (2,977 AUD) and receives $608 for utilities and maintenance, $2,744 a month in total OHA at the ceiling. With two dependents and 6 years of service, COLA adds about $1,291 a month. Both are tax-free.
OHA rent ceilings for every grade
OHA reimburses your actual rent up to the ceiling for your grade, so renting below it means a smaller payment, not money kept. Without dependents, the ceiling is 90% of the with-dependents figure.

Estimates use 2026 base pay at the years of service shown and DTMO's spendable-income table (CY2026 tables (effective Feb 1, 2026)). COLA = spendable income × (index − 100) ÷ 100 ÷ 12. Members without dependents living in government quarters receive a reduced rate. Run your exact grade, years of service and dependents in the OCONUS COLA calculator.
How Perth (Non-Adf Housing) compares
The COLA index of 144 is the 4th-highest of 29 Australia localities DTMO prices for OHA, and in the top 13% of the 624 locations worldwide that pay COLA.
Its E-5 rent ceiling ranks 6th of 29 in Australia.
Where the ceiling steps up with rank (with dependents): enlisted $1,833 for E-1 to E-4, $2,135 at E-5 (+$302), $2,439 from E-6 to E-8 (+$304), and $2,634 at E-9 (+$195); officers $2,135 for O-1 to O-2, $2,439 at O-3 (+$304), $2,634 at O-4 (+$195), $2,905 at O-5 (+$271), and $3,072 at O-6 (+$167). A promotion that lands before you sign a lease raises what you can rent.
At the ceiling, an E-5 with two dependents draws about $4,035 a month here in OHA and COLA combined, tax-free. The same member receives $2,061 in BAH at the median U.S. housing area. Treat that as a rough guide: OHA pays your actual rent rather than a flat amount, and COLA exists because everyday prices here run higher.
How these rates have moved
The COLA index has moved from 134 (August 1, 2025) to 144 (October 1, 2026). At 2026 pay, that is +$294 a month for an E-5 with two dependents.
| Effective | COLA index | E-5, 2 deps* |
|---|---|---|
| October 1, 2026 | 144 | $1,291 |
| August 16, 2026 | 140 | $1,173 |
