[1] The area now known as Hermidale is part of the traditional lands of Wangaaypuwan dialect speakers (also known as Wangaibon) of Ngiyampaa people.

[4] The area was originally known to settlers as Hermitage Plains but postal authorities substituted the name Hermidale, in 1892,[5] initially leading to some confusion with distant Armidale.

[6] What would become the village site lay astride the route of the Cobar railway line and a station was opened there in 1892.

The village retains a sports ground, tennis courts, post office, public school[9] and one hotel, and it has a small cemetery.

[22] In 2018, it was announced that Hermidale is the site of a new multi-user rail siding that will accommodate trains up to 1,200 metres long.
