AD PLACEMENT — CONTEXTUAL
Allow extra time if connecting from an international arrival to a domestic departure, as you must clear immigration and customs before reaching the domestic terminal.
Use the free Airtrain or Skygate shuttle bus rather than trying to walk between terminals, as they are not within walking distance.
Qantas and Jetstar international-to-domestic connections sometimes offer a streamlined transfer desk—check with staff at the arrival gate.
Domestic-to-domestic connections on the same airline within the same terminal can be quick if you avoid checked baggage.
Peak morning (6-9am) and evening (4-7pm) waves see the busiest security lines, so build in buffer time during those windows.

Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
The Airtrain shuttle connects the two terminals in about 5 minutes of travel time, while the free Skygate shuttle bus takes roughly 10-15 minutes including waiting. International arrivals must clear immigration, collect and recheck baggage, and pass through customs before reaching either terminal's security screening, adding significant time versus a same-terminal domestic-domestic transfer.
