Here's a few I picked up:
- Cruising Levels East/West instead of North/South. Odds when heading east in Aus. Effective from 5000ft.
- QNH zones numbered not named.
- Radio Calls the same but different. For example, calling ACD prior to entering Controlled Airspace with details.
- Rules structured in CARs and CAOs, even more difficult to navigate than in NZ.
- Forced to fly 3 legs of the circuit, or join via a 5 mile final at uncontrolled aerodromes (no joining base). No overhead joins (instead mid-field crosswind).
