There is an Android version:
Cairns Taxis – Apps on Google Play
Haven't tried it myself, but should be useful the next time I go to CNS.
True - it's happened quite a few times in Brisbane (not necessarily the airport... old taxi driver tricks in camping at the airport for jobs means there's rarely a job turned down when it's from the airport). Damn annoying really, but nothing much Uber will do about it, even if you report the driver.
It seems quite concentrated at Cairns and more particularly the airport. Usually, even if there are drivers playing that game, there are (in theory) a good decent number of others who aren't and will genuinely take your job and come to pick you up, viz. it shouldn't take 3 or more retries to get a genuine driver, particularly when an international flight has just arrived. It also doesn't make much sense to do the whole go around as Cairns airport and the city centre aren't terribly far apart unlike most other major Australian centres, and what would an Uber driver know anyway - they don't know where they are heading to until they have confirmed that the passenger has been picked up.
