What to pack for Australia

Sun protection is the single most important thing you'll pack

If your suitcase has room for exactly three things, make them a broad-brimmed hat, a proper bottle of SPF50 (or SPF50+) sunscreen, and a pair of close-fitting, UV-blocking sunglasses. Australia's UV index is genuinely, measurably among the highest in the world for large parts of the year, and it isn't tied to how hot the day feels — a cool, breezy, even cloudy-looking day can still carry a UV reading worth protecting against. Bring more sunscreen than you think you'll need; it's available everywhere locally too, but a familiar brand from home saves you a pharmacy stop on day one.

A UPF-rated long-sleeved shirt is worth the suitcase space as well, especially for anyone spending real time outdoors — it does more consistent work than reapplying sunscreen every couple of hours, without the sticky reapplication ritual.

Layer for the south's day/night swings

Sydney, Melbourne, Adelaide, Tasmania and the Red Centre all share one packing quirk: a genuinely warm day can drop into a cool evening, sometimes surprisingly fast. A light jacket or fleece layer earns its place in the bag even on a summer trip, especially if your itinerary includes an evening outdoors, a desert sunset at Uluru, or Tasmania's cooler, more changeable climate at any time of year.

This matters more the further you get from the coast — inland and desert regions lose heat fast after dark precisely because the dry air that makes the days so bright doesn't hold warmth overnight. A packable down or fleece layer takes up almost no space and solves this without overthinking it.

Reef days: sunscreen and swimwear, done right

If a Great Barrier Reef trip is on the itinerary, pack a rash vest or lightweight wetsuit top — hours spent floating face-down mean your back gets far more sun than you'd expect, more than sunscreen alone reliably covers. Most reef tour operators recommend, and often sell, reef-safe mineral sunscreen (zinc oxide or titanium dioxide based) rather than standard chemical formulas, since some common sunscreen chemicals are linked to coral damage at scale — worth packing your own reef-safe tube rather than relying on finding one at the last minute.

The tropical north: insects and humidity

Cairns, Darwin and the Top End run tropical and humid, and the Wet season in particular brings mosquitoes along with the rain. A DEET-based or picaridin-based insect repellent is worth packing (or buying locally — either is easy to find), along with a light long-sleeved layer for dusk, when mosquito activity generally picks up.

Quick-dry fabrics are worth prioritising for this stretch of the trip specifically — humidity means nothing dries overnight the way it might in the drier south, so a couple of quick-dry shirts save you from packing (or wearing) something still damp the next morning.

Footwear for the bush

Thongs — Australian for flip-flops, and worth knowing the local meaning before you ask for a pair at reception — are a genuinely good call for the beach and are everywhere here, but they're the wrong shoe for bushwalking, national park trails, or anywhere with loose rock, roots or the odd bit of wildlife underfoot. A pair of sturdy, closed, broken-in walking shoes covers everything from a short rainforest boardwalk to a proper day hike, and it's the one packing gap that actually limits what you can do on the day.

Power and connectivity

Australia uses Type I power sockets — three flat pins arranged in a triangle — which don't match the UK, US or continental European plug shapes, so a travel adapter is non-negotiable rather than optional. The mains supply runs at 230V, 50Hz; most modern phone chargers, laptop chargers and camera battery chargers are already dual-voltage and will handle that automatically, but it's worth a quick check on anything older or more specialised (hair tools are the most common exception) before you plug it in.

Getting online before you land is its own small project — worth sorting a local eSIM or SIM plan early so maps, translation and contactless payment apps all just work from the airport onward.

A few extras worth the space

A handful of smaller items round out an Australian packing list without taking up much room. A lightweight, packable rain jacket earns its keep in the tropical north's Wet season and in Tasmania, where weather can turn quickly regardless of the forecast. A basic first-aid kit — plasters, antiseptic, an antihistamine — is sensible for any bushwalking or road-trip-heavy itinerary, and a reusable water bottle is genuinely useful in a country with a strong refill culture in its cities.

If a road trip or campervan leg is part of the plan, a physical map or downloaded offline maps are worth having as backup — mobile coverage thins out fast once you're off the main highways, and it's better to have planned for that than to discover it mid-drive.
