This is new for me. My information, e.g. from the Paleogeographic
Atlas Project at Chicago University ( http://pgap.uchicago.edu )
indicates a clear separation of Antarctica from Australia and from
South America in Maastrichtian and already in Campanian.
There are land connections between Australian and Antarctica (via what
is now the Tasman rise) - you can actually see it on the LK map of
Chicago Atlas Project site but its hard to spot because it's stashed
away at the extreme bottom right - and between Antarctica and S.America
until well into the Eocene.
The presence of "condylarths", glyptodonts and phorusrhacoids on Eocene
Seymour Island graphically illustrates this (well between Antarctica
and S.America at least)
