For new students at UQ, with 100 Australian dollars, you can eat for about a week! Let me calculate it for you!
Breakfast: Eggs or a breakfast roll cost around 5 AUD.
Lunch: Chinese food at the cafeteria is around 10 AUD.
Dinner: Buy some fruits in bulk from the supermarket, which would cost around 3-4 AUD per day.
PS: Central Sizzle, Campbell Place (the location of the weekly campus market near the food court).
🥣Breakfast serving time:
Every Tuesday/Wednesday/Thursday from 8:00 am to 9:30 am.
🍝Dinner serving time:
Every Tuesday and Thursday from 5:00 pm to 6:30 pm.
(If you don't want to buy and wake up early, you can give it a try).
On weekends, you can cook at home, and buying groceries for three meals won't cost more than 10 AUD.
This is my personal eating habits and recommendations, feel free to adjust according to your preferences.
