[2] The origin of this name puzzled historians for many years because the clue lay not in Blacktown City but on Norfolk Island.

Governor Philip Gidley King had been in charge of the first settlement there in early 1788 and had noted that the hillside where he had built his Government House had been difficult to dig owing to the amount of tree roots beneath the surface.

[6] In 1891, the Pioneer Memorial Church, located on Rooty Hill Road South, was built on land donated by Dr Charles McKay.

[7] In 1902–1903, the School of Arts, located in Rooty Hill Road South, was built by the residents for community activities.

In 1973, the Whitlam government effectively abolished the White Australia policy, meaning people would not be denied immigration due to their nationality.

In 1964, the Rooty Hill RSL (now known as West HQ) was built, and over time turned into the largest licensed club in New South Wales, serving as a hub for entertainment, fitness and lifestyle.

Dubbed by some as the "Vegas of the West", the RSL also has Western Sydney's largest gym, five star accommodation and conference facilities.

Rooty Hill station opened on 23 December 1861 as the terminus of the Main Western line when it was extended from Blacktown.

In 2020, a station upgrade was completed, with renovated platforms, 4 lifts, a new concourse/footbridge replacing the old one, a 6 storey parking garage, and a facelift of the surrounding area.

Rooty Hill is served by buses which allow its residents to travel east towards Blacktown and throughout Mount Druitt and its satellite suburbs.

Woodstock Avenue connects Rooty Hill with Mount Druitt and Whalan, and also provides access to the Westlink M7 (M7 motorway).
