Dunmore is a largely rural suburb of Shellharbour City in New South Wales, Australia.

[2] Much of the present-day City of Shellharbour was originally part of the 13,000-acre Peterborough Estate, granted to discharged convict and colonial politician D'Arcy Wentworth in 1821.

Local shopkeeper George Lawrence Fuller bought the property and named it Dunmore after his birthplace in County Galway, Ireland.

[4] Dunmore came to prominence in 1887 as the location of the railway station serving the seaside village of Shellharbour, five kilometres to the north-east.

[5] The station moved from its original location at Dunmore Road, in the suburb's south, to be closer to the centre of Shellharbour, in 2014.
