I’m not sure I take your meaning. As best I can tell, it’s simply a Varonoi diagram centred on Australia’s cities of over 100k. The only complicated bit is how they chose the exact centre point of each city, especially Sunshine Coast and Central Coast. How the lines are drawn doesn’t seem to be based on any statistical data beyond that.

I don’t think “nearest city” is the best description.
It looks like, ABS identifies every urban area with at least 10,000 people, and then tags it with “the most relevant” centre in the region, or something like that.
So it’s something like, the way in which ABS divides localities into statistically useful segments.

Isn’t the city centre usually defined as the post office?

I don’t know for sure, but that doesn’t really sound true. It sounds like on of those “just so” stories. Like when people say the definition of a “city” is a place that has a cathedral.

It’s a Voronoi diagram. It’s nearest distance (in a straight line, not by road).
