Quick answer: For Southeast Asia, pack light in a 40–50L bag: a few quick-dry clothes you can wash every few days, a long layer for temples and cold buses, a money belt and a padlock for security, mosquito protection and a first aid kit, and an adaptor and power bank. Shop backpacker essentials.
Southeast Asia is one of the most popular backpacking regions for Australian travellers: affordable, accessible and varied. It rewards preparation. Before you go, register your trip with the Australian Government's Smartraveller service and check the advisory for each country you plan to visit.
Pack Light
Overpacking is a common mistake. Laundry services are widely available in towns across the region, so a few quick-dry items go a long way. Aim for a packed bag that's as light as you can manage, because you'll be carrying it through airports, bus stations and in the heat.
The Right Bag
- Check it fits carry-on limits for the budget carriers you plan to use, because limits vary by airline.
- A proper hip belt helps transfer weight.
- A clamshell opening is easier to pack than a top-loading pack.
- Lockable zips help in busy markets and on transport.

Clothing
- Quick-dry t-shirts in synthetic or merino. Cotton dries slowly in humidity.
- Shorts, one casual and one smarter.
- Lightweight long pants. Many temples require covered legs, and they help on cold overnight buses.
- A long-sleeve shirt for temples, evening mosquito cover and air-conditioned transport.
- Underwear and socks that dry fast.
- Sandals and walking shoes, or a pair that does both.
Packing cubes keep it organised. See our packing cubes and travel laundry essentials.
Security
- A money belt or neck pouch for your passport and backup cash
- An RFID wallet as a low-cost precaution
- A padlock for hostel lockers
- A phone lanyard or tether for busy streets
Health
- A first aid kit
- Mosquito protection. Speak to a travel clinic about vaccines and malaria risk before you go
- A water bottle, and use safe drinking water
- Sunscreen and any prescription medication with documentation
Sleep and Comfort
A sleeping bag liner or sheet is handy in budget accommodation, and a travel pillow helps on long bus rides.
Power
Bring a universal adaptor with USB ports and a power bank. Socket types vary within and between countries, so don't assume your Australian plug will fit.
What to Leave at Home
Heavy jeans, too many shoes and anything you'll only use once are all things you may end up carrying around for months.
