Plan your trips early as flights will likely be cheaper and some activities you plan on doing have early bird discounts. Look out for Jetstar’s Friday Fare Frenzy and Virgin Australia’s Thursday Happy Hour. Also, if you can, use the price tracker on Google Flights so you can get alerts when prices for flights you want become cheaper.
Pack light. Some airlines like to check the weight of your luggage (usually 7/8 kg or 15/17 lbs), so I suggest wearing layers during your plane ride or leaving unnecessary items behind.
Plan ahead. When you go to a new city or a new country, it can get overwhelming and you might be easily stressed. It is easier to book your hostels and hotels beforehand to alleviate some of that stress. Also, consider booking some of your activities to save time and avoid being turned away because all the spots are filled.
Australia is a big country. Consider domestic flights as they will likely be cheaper. It is also a great opportunity to explore other parts of Australia like the Great Barrier Reef, Melbourne, the Gold Coast, and more.
Take advantage of your location. Being in Sydney means you can travel to New Zealand, the South Pacific Islands, and Southeast Asia. It is a great opportunity to explore a different part of the world, learn about different cultures, and try new food. Flights to Southeast Asia are expensive but your daily cost will likely be low since food and accommodation are cheaper.
Explore more of Sydney. Sydney is so much more than just the walk to and from Science House and the beaches and the CBD. Do day trips from Sydney to places like Hunter Valley, Royal National Park, and Byron Bay.
Be spontaneous! There are so many hidden gems around Sydney that you could walk to or take a short bus or train ride to after class. You can also rent a car and drive if you want to get out of Sydney for a little bit. Just remember they drive on the other side of the road.
