Terrey Hills - Duffys Forest is well-off — but expensive to rent

Terrey Hills - Duffys Forest 2084 · Warringah, Greater Sydney, NSW

Terrey Hills - Duffys Forest is among the more advantaged parts of Australia (SEIFA decile 10 of 10); well served for the everyday — 8 schools and 1 supermarket. The trade-offs: renting is expensive, a median of $780 a week (DCJ, 2026-Q1); the population is barely moving — in fact it is shrinking.

Mostly free-standing houses, with a median age of 47 and households on a median $2,899 a week at the 2021 Census.
