Elevation is the ground at the locality centre, from Geoscience Australia's National Digital Elevation Model. Approximate — it reads high in dense built-up areas. It is a measure of height above sea level and not an indicator of flood risk, which depends on height above nearby waterways.
EV adoption
In postcode 4876, 0 of 1,042 registered light vehicles are battery-electric on 31 January 2025. A further 1.2% (12 vehicles) are hybrid or plug-in hybrid, taking the non-petrol, non-diesel share to 1.2%.
Rooftop solar
In postcode 4876, 37 rooftop-solar systems totalling 0.8 MW have been installed since 2001, against 804 dwellings recorded in the 2021 Census. 1 went up in the last year.
Counts every system certified since 2001, so a roof re-fitted with a newer system is counted twice, and small commercial systems are included alongside houses — useful for comparing postcodes, not an estimate of how many homes have working panels today.
2026 covers part of the year only, to 2026-07.
First Home Owner Grant
FY2026-27$30,000 for new homes priced up to $750,000.
$30,000 for contracts signed on or after 20 November 2023, with no end date. IT DID NOT REVERT TO $15,000: the tier was due to end 30 June 2026 and the 2026-27 Queensland Budget (23 June 2026) continued it for contracts signed from 1 July 2026. This file carried a "due to revert" note until 2026-09-18 — it was never true, and a note predicting a change is not the same as a change. Cap is "less than $750,000" including land and contract variations — less than, not up to. New homes only: "There are no home owner grants for established homes."
