During the Mesozoic Era
Yes.
Australia is a continent in its own right. It was once part of the supercontinent Pangaea, which broke up into Laurasia and Gondwanaland. Australia was part of Gondwanaland.
Antartica was located at the southernmost part of Gondwana. Gondwana was the southern landmass of Pangaea. It consisted of the modern day continents Africa, South America, Australia, India, Arabia, Antarctica, and the European Balkans.
Theory has it that Australia was once part of the super continent of Pangaea, the collection of all that we know today as the continents. Over time Pangaea broke apart and left Australia by itself. This allowed unique plants and animals to develop there (e.g. kangaroos).
When Pangaea split in two, there where two island landmasses. The Northern landmass was Laurasia. The Southern landmass was Gondwanaland.
Between india and antartica
There is no true answer, as Pangea split into two smaller continents: Gondwana and Laurasia. North America was a part of Laurasia while South America was a part of Gondwana.
Yes.
Gondwana
Yes. The Appalachians were formed by the same continental collision that created Pangaea.

Yes, because it was part of North America.
the part that it was located was in the middle of the equator.
