It is common for earthquakes to occur in Australia, as Mark Quigley and Januka Attanayake explains:
In Australia we get magnitude 5.8-6.0 or greater earthquakes, on average, once every four to 20 years. The highest since instrumental records began in Australia was the magnitude 6.6 quake in the Western Australia town of Meckering in 1968.
Earthquakes are considered a low probability, high consequence hazard — the rate of earthquakes is low compared to our seismically active neighbours in New Zealand, PNG, and Indonesia, but we have vulnerable infrastructure such as unreinforced masonry buildings that present a risk.
It was interesting to see the various responses to the situation:

The earthquake, which originated in Victoria, was felt in Canberra and Wellington.
That’s a blatant breach of the 10km radius rule and the earthquake will be fined.
