Australia is a long way from almost everywhere, so planning the journey matters. Distances inside the country are also large, so choose where you will land and plan any domestic flights early.
Australia at a glance
- Main gateways: Sydney (SYD), Melbourne (MEL), Brisbane (BNE) and Perth (PER).
- Busiest fare periods: December to January, Easter, and school holidays.
- Often better-value periods: March to May, and September to November.
- Seasons: reversed from the Northern Hemisphere, so June to August is winter.
When to fly
The Australian summer, from December to February, is peak season for beaches, festivals and school holidays, and the north is hot and humid with a wet season. Spring and autumn are often ideal in the south. Winter is the dry season in the tropical north, which makes it a popular time for the Outback and the Great Barrier Reef.
Routings and baggage
Qantas, United, Delta and American have flown non-stop or one-stop from the US West Coast and some other cities to Sydney, Melbourne and Brisbane, and some travelers connect through Honolulu, Fiji or New Zealand. Check baggage allowances on the exact fare, and on the domestic flights, which often have separate rules.
Airports and getting around
Sydney, Melbourne and Brisbane have rail links from their airports, and ride-hailing apps work in the cities. Domestic flights with Qantas, Virgin Australia, Jetstar and others connect the major cities, and driving distances between them are very long.
How to pay less on flights to Australia
- Avoid the Australian summer. December to February, Easter and school holidays are busiest. March to May and September to November are often the best mix of weather and value.
- Compare the non-stops with the connections. Qantas, United, Delta and American have flown non-stop or one-stop from the West Coast and some other cities, and some travelers connect through Honolulu, Fiji or New Zealand.
- Price the domestic flights separately. Distances inside Australia are large, and domestic flights often have separate baggage rules.
- Mind the biosecurity. Undeclared food, plants and outdoor items can mean heavy penalties, which would wipe out any saving.

Before you go
Check passport validity and Australia’s current entry rules through the official government site or app for every traveler, because many visitors need an authority or a visa before they fly. Australia’s biosecurity rules are strict, and you must declare food, plants, animal products and some wooden or outdoor items on arrival, or you can face heavy penalties. Sun protection matters. See the CDC page for Australia. Health notes reflect the CDC’s Travelers’ Health pages as last checked in October 2026, and notices change quickly.

Questions, answered.
When is the best time to fly to Australia?
The seasons are reversed, so December to February is summer and the busiest, most expensive period. March to May and September to November are often the best mix of weather and value.
How long is the flight from the US?
Non-stop flights from the West Coast take roughly 14 to 16 hours, and journeys from the East Coast take longer, with a stop. You also cross the date line, so you arrive a day later.
Do I need an ETA to visit Australia?
Many visitors need an electronic travel authority or a visa. Use only the official Australian government site or app, and check the rule for your passport.
