Schools
Universities nearby
Distance is measured to the suburb centre. A campus nearby does not by itself mean a student rental market — most suburbs within a few kilometres of one have a student share close to the national norm, and the figure above is what tells them apart.
Walkability
Birnam is very car-dependent on foot — at 4/100, nearly all errands require a car.
We hold no public transport timetable data for this area, so public transport is not rated here and the score is spread across the remaining components. It is not counted as zero.

Rooftop solar
In postcode 4352, 9,311 rooftop-solar systems totalling 64.7 MW have been installed since 2001, against 11,047 dwellings recorded in the 2021 Census. 597 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."
