North Avoca is built on the headland between Terrigal and Avoca Beach. Many homes sit on steep
slopes where sewer lines run downhill over long distances. Blockages build up at low
points and pipe joints shift over time from ground movement.

North Avoca sits on a narrow headland exposed to the Tasman Sea from both the east (North Avoca
Beach) and the north (Terrigal). This double salt exposure accelerates corrosion on all
external and under-floor plumbing.

With 83% owner-occupancy, North Avoca has one of the highest renovation rates on the Coast. 1960s
beach shacks are being gutted and rebuilt with multiple bathrooms, ensuites, and outdoor showers
— all requiring full plumbing rough-ins.
