Long Gully had several churches built throughout its history. A uniting church (originally a Methodist church) was built in 1877. In 1883, St Matthew's Anglican Church was built. A third church, the Church of Pius X, was built in 1956, and is now privately owned.

In 1873, the Long Gully Fire Brigade was formed. It operated from a fire station until a second fire station was opened in 1932; the first station was deregistered the same year.

It is the birthplace of Dick Richards, GC (14 November 1894 – 8 May 1986). Richards was an Australian science teacher who joined Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition in December 1914 as a physicist with the Ross Sea Party. He was 22 years old. He outlived all other members of the expedition and became the last survivor of the so-called "Heroic Age" of Antarctic exploration, dying at the age of 91 in 1986. His life-saving feats in the Antarctic are detailed in the book Shackleton's Heroes.
