A southern part of Llandilo was incorporated into an expansion of the suburb of Jordan Springs on 22 November 2019.

Prior to European settlement, what is now Llandilo was home to the Mulgoa people who spoke the Darug language.

They lived a hunter-gatherer lifestyle governed by traditional laws, which had their origins in the Dreamtime.

They hunted kangaroos and emus for meat, and gathered yams, berries and other native plants.

Shortly after the arrival of the First Fleet in Australia in 1788, an outbreak of smallpox decimated the local indigenous communities and made it easier for settlers to dispossess them of their land.
