Hubs matter
Sydney, Melbourne, Brisbane host the most connections. If you are crossing the country, assume at least one major hub unless you fly point-to-point on a budget carrier.
Bags and weight
Domestic Australia is strict on checked weight—read the kg allowance for your fare class. Carry-on size limits differ from US majors.
Time zones and same-day connections
Australia spans multiple zones—a “same day” connection on paper can mean a very long calendar day. Build 3+ hours for domestic self-transfers when you clear terminals.
Regional routes
Coastal hops can be cheap mid-week; Outback or regional legs may have fewer daily flights—book those first.
