No they don't. They come from the various states' geographical names
boards. Unfortunately, none of them appear to have released their
geodata, except via PSMA ($$$).

The current ABS suburb data are based on "mesh blocks" from the ASGS,
which are their smallest dividing buckets for census data. (The
pre-2011 ASGC suburb boundaries were made using a similar process.)
This means that their boundaries can deviate from the official state
boundaries, especially in sparsely populated or non-residential areas
where whole localities can even be missing altogether from the ABS

But they usually realign the boundaries when things like this happen.
