Lismore and Narromine NDB's a bit of fun
The old Mt ISA and Gunnedah NDB's were interesting with proceedure turns, Phillip Island with timed missed approach.
Alice Springs NDB would have to take the cake, two NDB's, a proceedure turn, timed missed approach point, followed by RH circling approach. Always a fun one to test students out on!
Tindal is not a difficult approach even with approach turned off.
