EV adoption
In postcode 4343, 26 of 11,343 registered light vehicles are battery-electric on 31 January 2025. A further 2.0% (231 vehicles) are hybrid or plug-in hybrid, taking the non-petrol, non-diesel share to 2.3%.
Rooftop solar
In postcode 4343, 3,701 rooftop-solar systems totalling 28.0 MW have been installed since 2001, against 4,461 dwellings recorded in the 2021 Census. 230 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.

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."
