Melbourne operating conditions that shape the plan
Melbourne's curfew-free main airport is the single most useful operating fact for time-critical work in south-east Australia, a mission blocked by a curfew elsewhere can often stage through Melbourne instead.
For patient transfers the absence of a curfew removes a common source of delay, so the limiting factors are usually crew availability, aircraft positioning and receiving-facility readiness rather than airport access.
- Melbourne Tullamarine (MEL/YMML) operates 24 hours with no curfew, which makes it one of the most flexible major ports in Australia for night movements
- Essendon Fields (MEB/YMEN) sits close to the city with a shorter runway and its own night restrictions, suiting smaller airframes
- Avalon (AVV/YMAV) is available as an alternate with long-runway capability and quieter slot pressure
- Winter fog and low cloud events can affect regional Victorian strips more than the main port
