Interesting situation....
I remember flying into Broome and overflew at 2000' to see which was the windsock was pointing (when it was uncontrolled), joined for a circuit, went around at about 300' as tailwind was too much, climbed to 1500' at did exactly what Tiger did to reposition for the other runway.....
