The suburb of Molonglo derives its name from an Aboriginal expression meaning "the sound of thunder".

It is planned to accommodate approximately 1000 new dwellings in a relatively compact mixed use urban environment.

[4] Molonglo is a cat containment area, as are other new suburbs in the vicinity.

This fault crosses the Molonglo River at the point where it goes in a tight bend from east to north west.

The rock south of the east–west fault is rhyodacite from the Deakin Volcanics, and to the north are the older Mount Painter Volcanics with tuff composed of dacite fragments.
