This post will cover remaining volcanic activity in southern Australia.  The majority of it is in the southeastern state of Victoria.  The most recent activity has spilled over the border to the west into South Australia.  Finally, we will take a look at volcanic activity in the Bass Strait, the water separating Tasmania from the rest of the continent and a quick look at volcanic activity in Tasmania.

I originally intended to cover all volcanic fields and provinces I could find in Queensland.  Turns out there were a lot of them, so many that the post grew too large.  Will limit this post to northern and central Queensland, and bundle southern Queensland with New South Wales in Part 3, the next post.  With that being said, let’s take a look at Queensland.
