Holy Trinity School is located in the township of Inverell, on the Gwydir highway, nestled on the banks of the MacIntyre River in the beautiful New England region of Northern New South Wales. The name Inverell, is of Gaelic origin, and means "Meeting place of the swans".
The Inverell district is in an agricultural region, also known for its sapphires, contributing to the majority of Australia's sapphire production.
Nearby is Copeton Dam, the district's main water supply. When this man-made dam is full it holds three times the capacity of Sydney Harbour, and as a result, holds quite a lot of fish. It is so large that when it is below 3% of its capacity during drought, it still has enough water to supply the town for up to ten years without water restrictions.
