AD PLACEMENT — CONTEXTUAL
Budget extra time if your connection spans different domestic terminals (T1, T3, T4), as this means exiting security and walking outside before re-screening.
There is no airport train — factor this into arrival timing if you're cutting it close, since ground transport delays can't be shortcut by rail.
International arrivals into MEL must clear passport control, collect checked bags, and pass through customs even if continuing onward — there's no sealed transit corridor.
Qantas domestic-to-international connections within Terminal 1/Terminal 2 are relatively smooth since they're adjacent, but still require a walk and fresh security screening.
If connecting between Jetstar (T4) and Virgin (T3) domestic services, allow generous time as these are on opposite ends of the terminal complex.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
All terminals sit side-by-side along a single landside terminal building, connected by a covered walkway of roughly 10-15 minutes end-to-end. There is no train or shuttle system — passengers walk the entire distance, and international arrivals must fully clear passport control, collect baggage, and pass through Australian Border Force customs before re-entering any secure zone, domestic or international.
