The Australian Plate
The Australian Plate are some of the more stable plates. The Australian Plate is one of the major plates and does't do much when it comes to moving around with their surrounding plates. Long ago though, they were not quite so stable. The eastern plate bobbed up and down because it had escaped the grip of the plate beneath it, which had been causing it to sink. This made the plate "jump up" and drain any seas that it had contained. Even when the oceans rose, it was still too high for any water to get on top of it. That's why it's so dry. Maybe that's also why it's so stable now. After it bobbed up, maybe it came down so hard it is now pretty much rooted there.
> Antarctic/Australian Boundary- This boundary is a divergent boundary. There are minor earthquakes here, but not any on a large scale. This boundary is not a particularly active scale.
> Pacific/Australian Boundary-This is a convergent bounday. The Pacific Plate goes underneath the Australian Plate. Here, the Kermadec Ridge marks the edge of the Australian Plate, and is made up of three volcanoes: Silent II, Healy, and Brothers.
>Australian/Eurasion Boundary- This is one of the plates that is north to the Australian Plate. There is currently no tectonic activity here.
>Australian/Indian Boundary-This plate is northwest to the Australian Plate and once again has no boundary mostly because as I said before, this is a relatively stable plate.
>Australian/African Boundary-This plate is to the west and, like the Indian and Eurasion plate, doesn't create volcanoes or earthquakes with the Australian Plate.
