Willows Oval was named after the long line of willow trees that run alongside the eastern side of the oval towards Sullivans Creek and Toad Hall (ANU).
Canberry Creek which ran through the property was renamed Sullivans Creek after William Sullivan (1829-1911).
The cleared part of the suburb has two arms, the east arm is the head of Sullivans Creek, and there is a larger northern arm.
