Cheer for the links villain
Overall though Australia is pretty much the safest continent in the world when it comes to earthquakes and volcanoes simply because we aren't near
any major plate boundaries. Most of the world's earthquakes and volcanoes are caused when an oceanic plate slips under a continental plate such as
around the Pacific Ring of Fire.
The boundaries of the plate which Australia sits on (the Indo-Australian plate) has its boundaries running through Indonesia to the north, NZ to the
east, Macquarie Island to the South and way off in the Indian ocean to the West.
Sure we have
had volcanoes in the past but the were relatively minor or occurred at a time when the palte boundaries ran down the eastern coast
of Astralia. Like anywhere though we can and do get earthquakes but these are more caused by a 'rumpling' of the the Indo-Australian plate rather
than major fault movement such as in LA with the San Andreas Fault (not saying that Australia doesn't have faults though).
