In postcode 7150, 677 rooftop-solar systems totalling 3.8 MW have been installed since 2001, against 2,064 dwellings recorded in the 2021 Census. 63 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

$20,000 for new homes.

$20,000 for transactions commencing 1 July 2026 - 30 June 2027. THE AMOUNT MOVES EVERY YEAR AND THE SRO PUBLISHES THE TABLE: $30,000 (FY2025-26), $10,000 (FY2024-25), $30,000 (Apr 2021 - Jun 2024). We held $10,000 until 2026-09-18, which was the FY2024-25 figure — two years stale, and wrong in both directions in between. Nothing is published beyond 30 June 2027, so this is due again then regardless of the 1 July sweep. No purchase-price cap is STATED on the eligibility pages (an absence, not an explicit "no cap"); the Grant Guideline PDF was not read. Eligible new builds include substantially renovated homes and kit homes. Completion within 24 months of the transaction start date, or the grant drops to $10,000. Separate from the grant: the first home buyer duty exemption on ESTABLISHED homes up to $750,000 closed for settlements after 30 June 2026.
