Unlike Hawaii, the youngest land on earth, or New Zealand which lies on the Pacific Rim of Fire Australia is not terribly close to volcanic activity.
The last volcanic eruption on mainland Australia was about 5000 years ago near Mt Gambier, although there are volcanoes in Antarctic Australian territories Big Ben on Heard Island and Mawson Peak on McDonald Island. Read more here, a learning web-based activity with lots of links.
I've been to Hawaii, and I've been to Chillagoe, North Queensland (many, many years ago, there are limestone caves there), but I have never visited the Australian lava caves at Undara. I'd love to go there!
So, now we have a Melbourne geologist warning that "Australia is long overdue for a volcanic eruption, and he says emergency authorities need to be better prepared".
Just quietly, I reckon there's a better chance of hell freezing over....
And I reckon we'll have some pretty good warning if we should have a volcanic eruption - there'll be plenty of seismic activity before the event. (I still think it's highly unlikey.) Earthquakes, yes... volcanos, no.
