If somebody had not noticed, if somebody had not done a massive retrofit, you would be still looking for the loo in the Sydney Opera House.
The date for the cave occupation, with the megafauna, is a great step in establishing human activity in Australia.
Adding what? 10,000 years to the record? And so far south? Amazing.
Some people did that in the Americas, pre-Clovis, and vanished almost (but not quite) without a trace.
I hope it turns out like the Australian experience = just an exploration gap.
