Fencing costs in Perth: what affects your fence

Much of Perth sits on the Swan Coastal Plain, where deep sands can make post holes collapse and need careful setting. Closer to the coast, limestone can sit near the surface and make digging slow and noisy, sometimes requiring different equipment. In the foothills and eastern areas, clay and gravelly soils appear.

Ask contractors how they plan to set posts in your soil and whether limestone or fill is likely on your block.

Strong afternoon sea breezes can load solid fences, so post size, spacing and footing depth matter. Long hot, dry summers are tough on coatings and timber finishes, and coastal suburbs add salt exposure.

The Perth Hills and parts of the metropolitan fringe are designated bush fire prone areas. In those areas, building rules referring to AS 3959 can affect materials used close to buildings. Check the state bush fire prone area map and your local government before choosing combustible materials.

Western Australian local governments apply local planning policies, and the state Residential Design Codes (R-Codes) influence front fences, generally favouring visually permeable fences above a certain height so streets stay open. Check your local government for current rules and any estate or heritage controls.

In Western Australia, local governments are responsible for inspecting private pool barriers on a regular cycle. Barriers must meet the standard that applies to your pool. Confirm requirements with your local government and the state building regulator before building or replacing a pool fence.

The Dividing Fences Act 1961 deals with neighbours sharing the cost of a sufficient dividing fence and the notice process. Check the current requirements with the official state source and keep written records of agreements.
