Well, another thing that is strange is that the whole of Australia is sitting in the middle of a plate. The nearest fault lines are in Papua New Guinea and New Zealand. It is possible to have a mid-plate earthquake but it is unusual.
Australia's largest recorded earthquake was in 1988 at Tennant Creek in the Northern Territory, with an estimated magnitude of 6.6. It occurred in a sparsely populated area and resulted in damage to a major gas pipeline.
On 21 May 2016, a magnitude 6.1 earthquake occurred in the Petermann Ranges region approximately 125 km southwest of Uluru in the Northern Territory. It was the largest Australian earthquake since a magnitude 6.2 was recorded offshore Collier Bay, Western Australia in 1997.
Is it odd that such a strong quake hasn't had aftershocks yet? Like it was just one... Blast?

yep, is just unusual, not impossible
