Retaining Walls in Hillarys
A marina-anchored coastal suburb around Hillarys Boat Harbour, on the northern coastal sand belt.
Retaining wall guidance for Hillarys homeowners - the right material for your site, and whether the WA 0.5 m permit threshold applies to your project. Hillarys sits in Perth's coastal limestone belt, where Tamala limestone-derived sand shapes most retaining decisions, which is the starting point for every material and compliance recommendation on this page.
Retaining Walls Perth Guidance for Hillarys
Hillarys sits on the northern stretch of Perth's coastal sand belt, anchored by the marina at Hillarys Boat Harbour. Established residential streets set back from the harbour carry the same stable-sand, geometry-driven retaining logic as the rest of the coastal zone.
Because Hillarys is a well-established suburb rather than a recent rebuild zone, a meaningful share of retaining enquiries here are repair or replacement work on walls built in the suburb's original 1980s-90s development phase, alongside new work.
Given the age of much of Hillarys' retaining stock, an assessment of an existing wall's drainage and footing condition is often the first practical step, ahead of deciding between a limestone or post and panel replacement. Hillarys sits within the City of Joondalup local government area; Joondalup's published guidance follows the standard 0.5 m WA exemption test, and for an older wall being replaced rather than a new build, it is worth checking with the City of Joondalup whether the replacement is treated as new work requiring a fresh permit.
For an older Hillarys wall, the practical sequence is usually assessment first, then a decision on repair versus full replacement, rather than committing to a rebuild before the actual cause of any visible movement is understood. A drainage-focused assessment in particular can sometimes turn a feared full-replacement job into a more modest repair.

About Hillarys
Hillarys is home to landmarks including Hillarys Boat Harbour, Sorrento Quay, West Coast Drive. The suburb's residential streets were largely established through the 1980s and 90s, giving it an older average retaining-wall stock than more recently developed coastal suburbs.
Local context for Hillarys
Streets around West Coast Drive and Whitfords Avenue in Hillarys were largely built out in the 1980s and 90s, which means a genuine share of the suburb's existing retaining walls are now 30-40 years old - old enough that repair-versus-replace is a live question for a meaningful number of Hillarys properties, not just a hypothetical.
