QLD state
Queensland
Queensland retaining-wall checks vary by council and by project conditions such as surcharge, nearby structures, boundaries, pools, services and drainage. Confirm the current local pathway for the property instead of relying on height alone.
See the Queensland guide →NSW state
New South Wales
New South Wales retaining-wall pathways depend on exempt-development conditions, the property constraints and local council controls. Start with the state criteria, then confirm what applies to the address.
See the New South Wales guide →ACT territory
Australian Capital Territory
ACT retaining wall planning can involve separate building-approval and development-approval questions. Start with the territory pathway, then use the Canberra guide for city site and enquiry preparation.
See the Australian Capital Territory guide →VIC state
Victoria
Victorian building-permit questions include wall height and possible effects on adjoining property. The actual site, boundary relationship and municipal controls still need an address-specific check.
See the Victoria guide →WA state
Western Australia
Western Australian retaining-wall thresholds and planning controls vary by local government. Identify the council area before relying on a rule or example from another municipality.
See the Western Australia guide →SA state
South Australia
South Australian retaining-wall planning starts with the address-based Planning and Design Code. Site overlays, boundaries, cut and fill, nearby structures and drainage can affect the assessment pathway.
See the South Australia guide →TAS state
Tasmania
Tasmanian retaining-wall categories depend on height, distance from boundaries and buildings, design and utility constraints. Check both building and planning requirements for the actual property.
See the Tasmania guide →NT territory
Northern Territory
Northern Territory permit requirements depend on whether the property is in a building control area, whether the wall supports building work and the retained height. Planning and other approvals may also apply.
