The town of Wellington is located at the junction of the Macquarie and Bell rivers. It is situated 410km by rail & 370km by road north-west of Sydney NSW. There is a daily rail service to and from Sydney.

Pre 1817, the Wiradjuri Aborigines lived in harmony with the land. Lieutenant John Oxley R.N, the Surveyor-General of New South Wales entered the Wellington Valley on 19 August 1817, after crossing the Catombal ranges, west of Wellington.

Oxley named the valley after Arthur Wellesley, the Duke of Wellington, in 1815. He further honored the Duke by naming three peaks in the Catombal Ranges, "Mount Arthur Reserve", "Mount Wellesley" and "Mount Duke".

The settlement was established on 24 February 1823, when a party of soldiers and convicts under the command of Lieutenant Percy Simpson started a convict station 3km south of the junction of the Macquarie and Bell Rivers.

The convicts were removed in 1831, and the settlement buildings were turned over to the  Missionary Society Mission. Wellington was gazetted a Town in 1846.

From this point on the town has grown to a population of 4,600 people today.
