The parish is located in Melbourne's inner east and also manages a campsite near Bairnsdale, Victoria on the Banksia Peninsula which is called ‘Coromorant by the Lakes’.

[4] The church is named in honour of Saint Hilary, Bishop of Poitiers in modern day France, who worked at evangelising the Roman region of Gaul.

[1][8] In 1929, the Nelson-Heintz Memorial Hall was opened which houses the Sunday school classes and former library for youth and children to develop their faith.

Later on, this was followed by St Augustine's Anglican Church, where there is now a large Chinese speaking congregation which Lead Minister, Stephen Hale fostered.

[13][12] On the morning of January 10, 2025, a fire broke out at the Kew site of the St Hilary's network, leading to significant damage to the main building.

The vicar, Adam Cetrangolo, alongside Fire Rescue Victoria and the local Boroondara Council, estimated the repair damages to be up in the hundreds-of-thousands, with no lives lost or injured.

[17] There is also an Op shop that the church runs with the St Hilary’s Hope subsidiary that provides donated clothing for disadvantaged people in the community.
