Mortdale, NSW 2223

Quiet, largely residential family suburb in southern Sydney, about 20 km south of the Sydney CBD and part of the St George area in the Georges River Council LGA. Named after the 19th-century industrialist Thomas Sutcliffe Mort, it grew from the 1880s - the local school opened in January 1889, the post office and grocery store in November that year - and became a popular residential suburb for soldiers returning from World War I in the 1920s, so much of the housing stock dates from the interwar and post-war decades. Mortdale's village centre is clustered around Mortdale railway station on Morts Road and Pitt Street, with the rest of the suburb mostly quiet tree-lined streets. At the 2021 census it had 10,745 residents, with a strong family profile: 50.3% of households were two-parent families, 37.3% of homes were owned outright and a further 31.8% were being purchased. The suburb runs south to Lime Kiln Bay on the Georges River, where the elevated Mortdale Heights locality (subdivided from 1924 and built out after World War II) takes in golf-course and waterfront outlooks.

At a Glance

Transport

Mortdale railway station sits on the Illawarra railway line of the Sydney Trains network and is served by T4 Eastern Suburbs & Illawarra Line services. Wikipedia's suburb article notes that 'Mortdale is a 30min (approx) train journey from the city' and that the suburb 'sits on the T4 trainline', which runs separately from the rest of the network and can help avoid delays. Buses fill the gaps around the train line: route 955 runs between Mortdale and Hurstville via Oatley with a stop at Mortdale Station on Pitt Street, and the U-Go Mobility-operated corridor routes 940, 941, 943 and 945 - which connect Hurstville, Penshurst, Lugarno, Riverwood and Bankstown - pass through the Penshurst/Mortdale area under contract to Transport for NSW.

Schools

Mortdale Public School - NSW government primary school, opened January 1889. Penshurst West Public School - NSW government primary school at Forest Road and Scott Street, whose campus is physically in Mortdale (NSW postcode 2223) despite its Penshurst name (Better Education; Good Schools Guide). Carinya School - NSW government school for specific purposes on the Mortdale Public School grounds, delivering programs for students aged 8-18 with intellectual disability and mental-health needs including anxiety and autism (Carinya School; EducationHQ). Marist Catholic College Penshurst - independent systemic Catholic co-educational secondary school (Years 7-12, around 1,000 students) whose campus at 65 Victoria Avenue is officially in Mortdale (postcode 2223) despite the Penshurst in its name.

Shopping & Amenities

Mortdale is mostly residential, with its main shopping centre on Morts Road and Pitt Street beside Mortdale railway station, plus some commercial and industrial development in the north-west corner of the suburb. The station village includes local shops and eateries, and listed local landmarks include the Mortdale Hotel, Mortdale RSL Club and the old Mortdale fire station and police station. The village centre is one of eight 'Local Centres' identified in the Georges River Local Strategic Planning Statement 2040, with council planning to grow shops, community facilities and housing around the station (Georges River Council).

Parks & Outdoors

Mortdale Memorial Park is the suburb's showpiece park, with a perimeter of large small-leaved fig trees, a classical rotunda and a decorative war memorial. Other local reserves include Renown Park - home ground of the Renown United Rugby League Club - plus Jubilee Park and Mick Downes Reserve. At the suburb's western edge, Hurstville Golf Course's 18 holes and the adjoining Ken Rosewall Tennis Centre (eight courts) sit between Mortdale Heights and the Georges River. The suburb's southern boundary reaches Lime Kiln Bay on the Georges River, and the elevated Mortdale Heights locality is bounded to the south by Lime Kiln Bay and Oatley Heights Park, with Beatty Street Reserve - partly an old quarry site cleared by the local progress association in 1954 - among its pockets of open space.

Property Market

The median house price in Mortdale was around $1,780,000 (median house sale price, based on 155 house sales over the 24 months to June 2026, NSW Valuer General records via PropertyGo) (mid-2026). See our full Sydney property price map for how the suburb compares across the city. Family-friendly market in line with the suburb's owner-occupier profile: houses gained +59.6% over 10 years and +28.0% over 5 years on PropertyGo's repeat-sales index, with roughly half of recent sales in the $1.5-2.0M band. Street medians range from about $1.10M (Bowman Street) and $1.18M (Forest Road) up to ~$2.27M on Scott Street and Jersey Avenue, while unit stock clusters along George Street and near the station (PropertyGo). OnTheHouse's suburb profile (5,550 properties) records +13.30% house and +23.11% unit growth over 5 years. Units are the dominant dwelling type on sale records (about 49% of sales) (AusPropertyFinder). Growth risk/opportunity centres on the Mortdale Local Centre Master Plan, which is working its way through the planning system to add housing capacity near the station (Georges River Council).

New Developments

Mortdale Apartments (Ellen Subway) - a seven-storey, 38-apartment building with ground-floor commercial space and basement parking, valued at about $25M, delivered by private developer Urbanlink on the south-western side of the Ellen Subway close to Mortdale station (Landpro Development Management). Mortdale Local Centre Master Plan - adopted by Georges River Council in October 2023 and being implemented through Planning Proposal 2026/0001 to amend the Georges River Local Environmental Plan 2021; the plan would rezone land for mixed use within walking distance of Mortdale station, lift height and FSR controls near the centre (including an R4 high-density area of up to 22 m / 2.2:1 FSR) and support roughly 773 new dwellings plus about 27,685 m2 of employment floorspace in the town centre (Georges River Council). The Department of Planning, Housing and Infrastructure rejected the initial proposal for not delivering enough housing uplift; councillors unanimously reaffirmed support for the plan in 2025 rather than withdraw it. Infill apartment blocks are also appearing on medium-density-zoned streets around the village, consistent with Mortdale's status as a designated 'Local Centre' in the council's LSPS 2040 (Georges River Council).

Jobs & Local Economy

Local employment is centred on the Mortdale village retail strip on Morts Road and Pitt Street - shops, eateries, the hotel and RSL - plus the light commercial and industrial pockets in the suburb's north-west corner. Most working residents commute out of the suburb: T4 trains put the Sydney CBD about 30 minutes away, and Hurstville - the St George area's main commercial centre - is the next stop north on the line and a short bus trip via routes 955 and 945.
