During the Cretaceous, the North American plate was further north (closer to
the Arctic circle),
and Australia was further south (closer to the Antarctic circle).
As far as I know, Antarctica has always been close to the south pole. It has
wandered about a bit,
but it has been in the general vicinity for a long time.
