Mortlake sits on the southern bank of the Parramatta River and is home to the southern bank of the Mortlake Ferry or commonly known as the Putney Punt, the last surviving punt service in Sydney.
Mortlake is also the terminus for bus route 464 (to Ashfield railway station).
Mortlake was notable as the site of the Australian Gas Light Company (AGL) gas works, which first purchased land here in 1883. Colliers from Newcastle or Hexham brought coal to the gasworks wharf at Mortlake. When a new Gladesville Bridge was opened in 1964, it was built to replace a bridge that needed to close every time the swing section on the southern end of the bridge had to be opened to permit large vessels to pass through. The gas works closed and the land redeveloped into the Breakfast Point residential development, which since 1993 has been a separate official suburb.
In the 2016 Census, there were 1,954 people in Mortlake. 57.7% of people were born in Australia and 57.7% of people spoke only English at home. The most common responses for religion were No Religion 32.5% and Catholic 31.7%.[1]
