Castlemaine is one of Victoria's most architecturally significant gold-rush towns — about 120 kilometres north-west of Melbourne via the Calder Freeway and V/Line Bendigo line. The 1851 Mount Alexander gold rush was one of the richest alluvial discoveries in history, and Castlemaine's legacy includes some of the most intact Victorian-era streetscapes in regional Victoria. The Section 32 framework reflects extensive A-grade Heritage Overlay coverage, documented underground gold-mine workings, and Environmental Audit Overlay (EAO) arsenic disclosures from historical gold-processing — the same pattern as Beechworth and Sebastopol.
This guide covers the Section 32 and Contract of Sale issues specific to Castlemaine (postcode 3450, Mount Alexander Shire).
Castlemaine at a glance
- Council: Mount Alexander Shire (its own planning scheme).
- Postcode: 3450.
- Buyer profile: tree-changers, hospitality investors, V/Line commuters, retirees, creative-industry professionals (Castlemaine has a substantial arts / maker community).
- Dwelling mix:1850s/60s heritage commercial and residential, miners' cottages, larger Federation/Edwardian homes, smaller new infill.
- Median house price (indicative):approximately $700k–$960k for established homes; A-grade heritage substantially higher.
The dominant risk: A-grade Heritage Overlay across the town
Castlemaine's commercial precinct (Mostyn Street, Hargraves Street, Barker Street) and adjacent residential streets carry substantial A-grade and B-grade Heritage Overlay gradings. Practical implications match Beechworth and Clunes:
- Demolition essentially prohibited on cited buildings.
- External alterations require detailed council scrutiny.
- Restoration must use period-correct materials at premium cost.
- Sub-division of heritage lots commonly prohibited.

Secondary risk: gold-mining legacy + EAO arsenic
Substantial parts of Castlemaine sit above documented underground gold-mine workings. Some lots are affected by EAO from historical gold-processing arsenic contamination. The Section 32 should disclose both.
Tertiary risk: Section 173 commercial / B&B
Many heritage buildings operate as cafes, restaurants, accommodation, or retail under Section 173 Agreements.
