Alice, you've explained nothing.
Everybody - even the beknighted Awake agrees - that the land masses were connected at one time. That doesn't explain why all these strange animals ended up in Australia, especially so many with pouches.
"Any island"? It looks to me like the bigger the island, the more opportunities for evolution to make weird stuff. You can start with the different finches, etc in the Galapagos - then move on to lemurs, etc in the bigger Madacasgar - and then hit the 'almost a continent by itself' Australia, where the really weird stuff congregates.
I once officially asked a Creationist society about Australia and they had no answer either.
Let me add a fourth easy disproof of the new brochures while I'm at it:
4) Evolution has been directly observed by science - I rejected evolution for decades because science couldn't come up with a new fertile species that can't reproduce with the parent species it was breed from. That's been overcome more than once. And that, to me, is the critical definition of what evolution is. I followed the evidence where it led.
