Alex has made some adjustments to his Alpine algorithm for TextMapper to get better desert terrain – e.g. Australian. Lots of generic rpg maps assume European type things – e.g. cool to cold, whereas Australia is temperature to equatorial, in general.
This one is a nice example https://campaignwiki.org/text-mapper/alpine/document?width=52&bottom=3&peaks=7&bumps=2&height=48&steepness=4&peak=10&bump=2&arid=0&climate=desert&type=hex&seed=693329917
