Tips for 45 min Connections
Never book a tight international-domestic connection at SYD unless it's on the same Qantas itinerary with through-checked bags and status recognition.
If flying Qantas internationally into a Qantas domestic connection, look for the dedicated transfer desk that can streamline immigration and bag handling.
Use the free T-Bus rather than walking if connecting between T1 and T2/T3, as there is no direct walkable path.
Build in extra buffer for immigration queues at T1 during the early morning wave of long-haul arrivals from 5-8am.
T2 and T3 are internally connected, so domestic-to-domestic transfers on different airlines are far easier than any connection involving T1.

Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
A free T-Bus shuttle runs between T1 and T2/T3 every 10 minutes and takes about 10-15 minutes depending on traffic, while the Airport Link train is a paid alternative that takes around 6 minutes but requires fare gates. T2 and T3 are connected by a covered indoor walkway (5-8 minutes). Passengers connecting from international to domestic (or vice versa) must clear Australian immigration, collect and recheck bags, and pass through security again, as there is no sterile transit corridor for most travelers.
