EV adoption
In postcode 4184, 25 of 10,765 registered light vehicles are battery-electric on 31 January 2025. A further 0.8% (81 vehicles) are hybrid or plug-in hybrid, taking the non-petrol, non-diesel share to 1.0%.
Rooftop solar
In postcode 4184, 3,620 rooftop-solar systems totalling 18.8 MW have been installed since 2001, against 5,157 dwellings recorded in the 2021 Census. 240 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."
Mortgage repayments

Transfer duty at the owner-occupier rate, and it excludes first home buyer concessions — those can cut it substantially or remove it entirely. Excludes legal, inspection and lender fees. Check with Queensland Revenue Office
The First Home Owner Grant applies to newly built homes only, so it isn't available on an established purchase. A first home buyer building or buying new under $750,000 may qualify for $30,000 — see what qualifies with Queensland Revenue Office.
At $472,500 this is under the $750,000 First Home Owner Grant cap. A first home buyer may qualify for $30,000 on a newly built home — check eligibility with Queensland Revenue Office.
