I am inclined to agree 5,600 BC coincides, I believe, with the eruption of Mt. Mazama (Crater Lake) which left a 6 mile wide caldera. Lots of dust in the northern hemisphere to serve as nuclei for catastrophic rains and floods. Just look at what we have been having in our own middle west this year, not to mention the 500 year flood of the Mississippi after Pinitubo.

I saw a tv show on that yesterday. Australia generally got drier and wetter with the coming and going of the ice ages in the north. The map I saw did show a section in the south east corner of the continent that did experience some glaciation. the show I saw yesterday discussed the demise of the megafauna in australia about 46000 years ago. the question was why did they die — given that there had been many periods of wet and dry before that they survived. they weren’t definitive but its thought that perhaps habitat loss—during a dry spell— brought on by slash and burn techniques of the recent arrivals the aborigines—may have tipped the balance.
