Australia, New Zealand & the South Pacific - Uluru/AS/Red Centre - Ok in Oct.?

I've been reading that the best time to go is May-September. Is October too late to go there, ie is it too hot? If so, we can save it for another trip.

It will be 100 but not 120. You have to decide what OK means to you. Lately it has been hotter than average, fwiw.
