You can live on 1350 but your life will be simple. For example
Rent hostel 650
Electricity/Soap/Household stuff 100
You are left with 600 per month, or 20 per day.
You wake up, eat breakfast at the canteen for $4, have lunch, say MacDonald's meal $8, and have dinner say fish and chips in school for $6. That is about $20 a day.
Sometimes you need to see a doctor ($50), go to a pub ($30), buy some nice clothes or stuff...those you have to draw on your savings.
