A little bit of history
 

Prior to white settlement the area the Coolah valley was occupied by the Kamilaroi and Wiradjuri peoples. In 1823 explorer Allan Cunningham became the first known European in the district when he came across Pandora's Pass, the route over the Warrumbungle Range on to the Liverpool Plains. The district was surveyed in 1832 and squatters soon followed, in search of fresh pastures.

The town site of Coolah was first occupied in the 1840s. By 1848 there was a slab blacksmith's and a slab hotel. Local sandstone was used to construct more substantial buildings in the 1870s.  
The railway did not arrive until 1910. Before that time, travelers en route to Sydney had to journey by a horse-drawn vehicle to Mudgee, by Cobb & Co coach to Penrith and then by rail to the city.  
Today the railway is just a remainder to people of its past purpose. 

Coolah is the principal town of the Former Coolah Shire( Now  Warrumbungle Shire) It is situated by the Coolaburragundy River, 89 km north-east of Mudgee and 352 km from Sydney. It functions as a service centre to the surrounding district which is given over to the production of wheat, cattle, mixed farming, timber, fat lambs and wool. Our timbered areas yield Cypress Pine, Stringy bark and Ironbark.
For the keen Philateist, Coolah boasts its own pictorial post mark pictured bellow
