Gymea Bay, NSW 2227

Quiet, leafy, bayside suburb of the Sutherland Shire about 27 km south of the Sydney CBD, taking its name from the small bay on the north side of the Port Hacking estuary that fringes its peninsula. Gymea Bay grew around wharf and boat access to Port Hacking after the railway reached Sutherland in 1885, then developed into a recreation and holiday area of fishing shacks before maturing into a settled, mostly residential family suburb; since the 1980s incremental subdivision has replaced older houses with larger family homes. The 2021 census counted 6,983 residents in a housing stock dominated by separate houses, with a high-income profile — median weekly household income of $3,047 against the national figure of $1,746. The community centres on the heritage Gymea Bay Baths, creek-side bushland reserves and the Port Hacking waterfront, with day-to-day needs served by the adjacent suburbs of Gymea and Miranda.

At a Glance

Transport

Gymea Bay has no railway station — the suburb is a residential peninsula served by Gymea Bay Road — and the nearest stations are Gymea and Kirrawee on the T4 Eastern Suburbs & Illawarra (Cronulla) line, both in suburbs immediately adjoining Gymea Bay. Buses run along Gymea Bay Road, connecting the peninsula to Gymea railway station and the surrounding centres, and quickproperty counts about 20 bus stops within the suburb (quickproperty; The Leader). Gymea station is heritage-listed and its T4 services run through to the Sydney CBD and Bondi Junction (Gymea railway station).

Schools

Gymea Bay Public School — NSW government primary school on Gymea Bay Road, opened August 1935 with 65 students and relocated in 1955 to its present site near June Place (entry via 205A Gymea Bay Road); as of 2025 it is the largest primary school in the Sutherland Shire, with 752 students and 75 staff, and it is the suburb's only school. There is no secondary school within Gymea Bay; government secondary students are zoned to Port Hacking High School in the immediately adjacent suburb of Miranda, and the nearest Catholic primary options are in adjoining Gymea and Miranda.

Shopping & Amenities

Gymea Bay's own retail offer is limited to a small group of local shops in Casuarina Road, near its intersection with Gymea Bay Road, and the suburb is principally served by the commercial centres of its immediately adjacent neighbours — the Gymea village centre around Gymea railway station (cafes, restaurants and boutiques along the Gymea Bay Road/Kingsway strip) and Westfield Miranda, one of Sydney's largest regional shopping centres, in adjoining Miranda. A community hall, playground and tennis courts developed around the old Casuarina Road settlement core, and a church hall (St Barnabus) still stands on Gymea Bay Road.

Parks & Outdoors

The suburb fronts Gymea Bay, an inlet of the Port Hacking estuary, and the bay and river are used extensively for recreation, fishing and boating. Heritage-listed Gymea Bay Baths sit on the shore at the Gymea Bay Baths Reserve at the corner of Gymea Bay Road and Ellesmere Road, and have been used by the Gymea Bay Amateur Swimming Club for over 40 years. Coonong Creek Bushland Reserve — remnant bushland maintained by Sutherland Shire Council and volunteers — runs through the suburb with walking tracks linking Old School Park and the Gymea Bay Baths Reserve.

Property Market

The median house price in Gymea Bay was around ~$2.0–2.2M (sold-median trackers, 2025–26): YIP reports a median house price of $2,190,000 (92 house sales over 12 months); quickproperty's Valuer-General/ABS-based dataset puts the median at $2.0M, broadly unchanged year-on-year (mid-2026). See our full Sydney property price map for how the suburb compares across the city. Gymea Bay is a tightly held, low-turnover house suburb (roughly 90 house sales in 12 months) with waterfront and bay-view houses along the Port Hacking side trading well above the median. Trackers differ materially by method: sold-median sources cluster around $2.0–2.2M while AVM 'value' estimates run higher, so a realistic planning range is roughly $2.0–2.6M depending on position and method. The unit market is negligible — mostly houses on larger blocks, increasingly subdivided since the 1980s.

New Developments

Minimal — Gymea Bay is an established, fully built-out low-rise residential suburb with no significant current development pipeline; since the 1980s the main change has been incremental subdivision and knockdown-rebuilds of older houses on larger blocks. Sutherland Shire Council's planning record shows no major residential projects within the suburb.

Jobs & Local Economy

Gymea Bay is essentially a residential commuter suburb with little local employment. Residents work mainly in the retail and services hubs of the immediately surrounding Sutherland Shire centres (Gymea village and Westfield Miranda are the suburb's principal shopping destinations) and in the Sydney CBD via the T4 railway from nearby Gymea station. The high-income profile — median weekly household income of $3,047 at the 2021 census against the national $1,746 — reflects a large share of professional and managerial commuter households.
