Average rent in Thornlie, WA — 2026

Thornlie runs roughly with the Western Australia state median — renters typically pay $330/week, close to the $337/week state baseline (ABS Census 2021). Most households here own (76% are owners or paying off a mortgage) and only 21% rent. Separate houses dominate the housing stock (91%), which gives the suburb a quieter, family-leaning feel — borne out by a median age of 38 and a population around 23,665. The most common occupation is Technicians and Trades Workers, and 42% of residents were born overseas. Thornlie is 15km from Perth, and rent trajectories here tend to track the state average rather than running ahead of it — but state rent indices have moved since 2021, so double-check against the live figure above.
