Sydney is a very expensive city to live in and even as a student I would suggest you budget for a daily allowance of $50 food only. Travel expenses can be approx $50/week. You can buy an unlimited bus/train/ferry ticket for $41 if you plan on staying in the city area. Entertainment is where you'll get stung - alcohol is expensive, as are the movies and most tourists spots. about 8 years ago
Where in Sydney are you looking to stay? There is a cute one down at the Rocks (near the Harbour) http://www.bbsydneyharbour.com.au/ but would also recommend looking around Paddington area as well. Close to the city, beaches and a little quiet. about 8 years ago
