Colinton is a locality in the Snowy Monaro Region, New South Wales, Australia.

[4] In June 1823, an exploration party, composed of Captain Mark Currie, Major John Ovens, Joseph Wild and an unknown Aboriginal guide, followed a route to the east of the steep slopes of the Murrumbidgee River's gorge and were the first colonists to pass through the area.

[5] Although the area was just outside the southern boundary—Michelago Creek—of the Nineteen Counties, in which settlement was allowed by the colonial government, it was suitable for sheep grazing.

[7][8][9] In the late 1860s, the Colinton field was being worked mainly by Chinese miners.

[23][31] During construction of the railway from Michelago to Cooma, most of the major works—four bridges, a tunnel and some cuttings and high embankments—lay between Michelego station and the far side of the Bredbo River.

[32][33][34] The discovery of a gold reef in 1888, by employees of the railway construction contractor, led to desertions from the camp as workers and locals staked claims.

[37] However, in 1891, Colinton was described, by a visitor, as a mining hamlet "whose glory was departed, now left a prey to goats, pigs, and fowls".

[49] A fatal accident occurred in the 1890s involving a man hit by a passing train while stuck inside the tunnel on horseback.

[50][23] Since 1989, there has been a Rural Fire Brigade at Colinton, with its shed located within the site of the former village.

The disused Bombala railway line still passes just to the west of the old village's site and the remnants of the old level crossing at Newton Street can still be seen, as can the wooden railway bridges over Ingalara Creek[57] and Colyers Creek.

To the north, on the Monaro Highway, where the old railway once crossed that road, is the Colinton Rest Area.
