The Manse is a heritage-listed former residence and now community museum at 23 The Avenue, Mount Druitt, City of Blacktown, Sydney, New South Wales, Australia.

[1] The Mount Druitt area played an important part in the early colonial history of New South Wales.

It was one of three areas along with Prospect and Colyton, clustered some 45 kilometres (28 mi) west of the Sydney Cove settlement at Port Jackson.

Macquarie appointed him colonial engineer and inspector of public works, and he supervised construction of many of architect Francis Greenway's buildings.

It comprises a single storey brick residence in rectangular plan, distinctly Victorian Georgian in architectural style, with hipped roof and skillion verandah on two sides.

Reverend George Milne occupying The Manse from about 1913 until 1930[4][1] After a split in the Church, Blacktown City Council bought the house in 2001 and rented it out as a residence.

[6] A very fine and largely intact early country style dwelling, it is the oldest remaining building in Mount Druitt.

[1] Although no flora survey was prepared as part of the plan of management process, the remnant native trees area consistent with the vegetation community found at the nearby Dr. Charles McKay Reserve at Beames Avenue, Mount Druitt which is dominated by grey box (Eucalyptus punctata) and narrow-leafed ironbark (E.crebra) Woodland.

[1] Although little endemic understorey exists on site; the remnant native trees are consistent with this community and may have potential for regeneration.

The typical structure of the community would be scattered woodland to open forest and the understorey characterised by the shrubs blackthorn (Bursaria spinosa), spider flower (Grevillea juniperina), ham and eggs (Pultenaea microphylla) and the pea flower, Dillwynia juniperina.

The car park and associated fencing on the corner of Mount Druitt Road & The Avenue are partially within the Reserve boundaries.
