Reids Flat is a historic village, originally known as Numby, in regional New South Wales located within Hilltops Council.

Active bushrangers in the area during the early 1860s included Jack Peisley and Frank Gardiner, who often sought refuge at the farm of William Fogg.

Caves within the surrounding rocky mountains provided excellent hiding places for the bushrangers – it was claimed that girlfriends and wives would hang white washing on the lines in the valley when the coast was clear.

[6] Local merino sheep wool production is amongst the finest in the world, with the majority of 15 micron fleece pre-sold to the Italian fashion market.

The village – a quiet residential area – does not have any commercial establishments within its boundaries; the nearest shop is located 22 kilometres (14 mi) away, in the town of Bigga.
