Australia Travel Guide: The ETA, Strict Biosecurity, and What to Know Before You Go

EU passport holders (plus UK, Norway, Iceland, Switzerland and a handful of others) use the free eVisitor (subclass 651) — online only, multiple entries over 12 months, up to 3 months per visit. US, Canadian and several other passports use the ETA (subclass 601) instead, an app-based authorisation with a small service fee, also valid up to a year with a 3-month-per-visit limit. Both are for tourism or short business only and must be arranged before you travel — apply only through the official Australian immigration channels, never a third-party site.

Australia has one of the highest contactless payment adoption rates anywhere — tap-to-pay works for nearly everything, even small purchases, and a foreign card or phone wallet is generally all you need. Cash isn't necessary for most trips, though it's still worth having a small amount for the rare exception.

Given the distances involved, domestic flights are the practical way to cover long inter-city routes — Perth to Sydney, for example, is a several-hour flight versus days overland. Long-distance trains like the Indian Pacific or The Ghan exist, but function as scenic, iconic journeys rather than a practical way to get somewhere quickly; public transport within capital cities is solid but drops off fast outside them.

Tipping is not customary — staff are paid a legal minimum wage and aren't tip-reliant. It's optional and has crept in slightly in some cities, but there's no expectation either way.

Australia's biosecurity rules at the border are unusually strict and worth taking seriously: all food, plant, wood and animal products must be declared on arrival, even things that seem harmless like packaged snacks, a wooden souvenir, or hiking boots with soil on them. Declaring an item that turns out to be prohibited just means it gets taken — not declaring it, or declaring falsely, is what triggers a real, escalating fine. When in doubt, declare it.

Australia is in the Southern Hemisphere, so seasons are inverted from North America and Europe — summer runs December to February, winter June to August. The temperate south (Sydney, Melbourne, Tasmania) has a classic four-season climate, best for beaches in summer or mild sightseeing in autumn/spring; the tropical north (Cairns, Darwin, the Reef) runs on wet season (roughly November-April) versus dry season (roughly May-October) instead.

Wildlife risk is real but manageable with normal precautions, not the horror-story version sometimes portrayed: marine stingers are present in tropical Queensland waters in stinger season (roughly October/November to May/June) — swim at patrolled, netted beaches. Crocodiles inhabit estuaries and some beaches across northern Australia — heed warning signs and don't swim in unmarked waterways in croc country. Snakes are common but bites are rare if you wear closed shoes and don't provoke them.
