It's a toughie. For hotspot maps to be useful, they have to be granular (I'd say SA1, you could maybe get away with SA2). If granular, you risk people's privacy

For reference, the average population of an SA2 is about 10,000 people and includes entire towns. Not useful when an 'outbreak' could be a few dozen people - you really need that SA1 data (~400 people)

Fully understand (ex-GIS researcher here) but that leaves us in primary in a hard place - without knowing the hot spots we make assumptions (ie Melbourne a hot spot and therefore I screen everyone?). Nice wording (screen hot spots) but no practical follow-through (how).

What is SA1 and SA2?
-
Statistical Area codes. They define the geographic spread of people in Australia, used by the ABS. Like postcodes, but more useful and specific
