The USA is one of the most popular long-haul destinations for Australians — and also one of the trickiest to pack for. From the plug differences and massive geographic size to the varied climates and TSA rules, here's the complete guide to packing for an American trip from Australia.
The Adapter Situation: Critical to Get Right
Australia uses Type I plugs at 240V. The USA uses Type A/B plugs at 110V. Your Australian plugs physically won't fit US sockets without an adapter. Most modern Australian electronics (phones, laptops, cameras) are dual-voltage and handle 110–240V automatically — but check the label on each device before you go. If it says "Input: 100–240V" you're fine. If it only says "240V" you need a voltage converter as well as a plug adapter.
The PlugMate™ Universal Travel Adapter handles the physical plug conversion for 200+ countries including all US States, with USB-A and USB-C fast charging built in. One device for your entire trip regardless of how many states you cross.
Packing for America's Climate Diversity
The USA spans 6 time zones and multiple climate zones. New York in October is 10–18°C. Miami in October is 28–32°C. Los Angeles year-round is 18–26°C. Denver can snow in October. Pack for your specific destinations, not "America" as a concept:
- East Coast (NY, DC, Boston) spring/autumn: Layers — 15–22°C days, cool evenings. A light jumper and waterproof jacket are essential.
- California: Mild year-round. Light layers for San Francisco fog, t-shirts for LA and San Diego.
- Florida / Hawaii: Tropical. Pack light — swimwear, shorts, light shirts.
- Vegas: Desert climate — hot days, surprisingly cold nights. Layers work well.
PackEase™ Compression Bags are especially useful for multi-city US trips where you need clothing for different climates without overpacking.

TSA Rules for Carry-On
US TSA rules apply at all US airports:
- Liquids: containers must be 3.4oz (100ml) or less in a single 1-quart (approx. 1L) clear zip-lock bag
- Laptops and large electronics must be removed from your bag and placed in a tray
- Shoes typically must be removed at security (not always required in Australia)
- TSA PreCheck lanes (if you have it) skip these requirements — not available to Australian travellers without a Global Entry membership
Luggage Security
US domestic flights often involve checked bags on longer routes. Use TSA-approved luggage locks — TSA inspects checked bags routinely and will cut non-TSA locks without hesitation. The CodeSafe™ Luggage Strap prevents bags from opening if locks are removed during inspection.
RFID Protection
Credit card skimming exists in the USA, particularly in tourist-heavy areas and at gas station card readers. Keep cards in your ZenShield™ RFID Card Wallet and your passport in your JetPocket™ Passport Wallet.
What to Know About US Domestic Flights
If your US itinerary includes domestic flights (very common on a multi-city trip), US domestic carry-on rules are generally more relaxed than international — most major carriers allow one bag + one personal item with no strict weight limit. However, basic economy tickets on Delta, American and United often restrict you to one personal item only. Check your fare class carefully.
