There are at least two Portuguese-named Flores islands; we're dealing with the one with hobbits. We now have a record of its climate and of its elephant population.
The Liang Bua clock starts 190kya, for humans anyway (I don't know about before that). After the MIS 5e which we used to call Eemian, this release offers more detail:
We found three key climate phases. It was wetter than today year-round between 91,000 and 76,000 years ago. Between 76,000 and 61,000 years ago, the monsoon was highly seasonal, with wetter summers and drier winters. Then, between 61,000 and 47,000 years ago, the climate turned much drier in summer
After that it gets silly by talking "southern Queensland", as if that part of Australia had the same climate over that stretch. Weak sauce, mates. Maybe instead relate this to Timor.
The Floresian parahumanity limped along as scavengers. Until 48kBC sometime around which, one of Indonesia's volcanoes went boom - and that was it. It wasn't Toba 72kBC; but whatever it was, Flores now went under new management. That first human population might have been like Timor's then; nowadays the "central Malay/Polynesian" cluster has pretty much swamped all those islands.
