Unlike TV surveys which evolved from a diary system to the OzTam set top box, radio surveys to my understanding are still pretty much the same as they were 20 years, a personal diary system.
The regular surveys are run by Commercial Radio Australia and ONLY commercial radio stations are listed.
They are broken up into very broad timelsots
Weekdays - Breakfast, Morning, Afternoon, Drive, & Evening.
There is also a segment surveyed for Weekends - 5.30am to 12 midnight.
this is not broken down any further to tell who is listening to say commercial footy coverage or how a particular show rates.
So even FIVEaa or TripleMMM could not tell you how many were listening specifically to their footy coverage, only their average weekend audience across those 37 hours each week.
The commercial radio survey does not include community stations.
Here is a link that run by the Community Broadcasting Assoc of Australia
It is about community radio in general, not specific stations let alone shows.
