With a tropical influenced climate, Australia is best enjoyed with layered clothing. Tees, shorts, and jeans should be comfortable enough for most days.
You’ll have to take your own bedding, toiletries, and kitchenware as most student housing provide only a mattress with the bed.
When you pack for Australia, definitely throw in a sunscreen with high SPF. A hat and sunglasses are also important to protect your skin
Laptops, cameras, and any other electronics that you plan to bring will need to be plugged in with a suitable power adapter, so make sure you get one.
