Had a similar experience in Sydney. I was able to buy one week's groceries for just 70 AUD (Salary for 3hrs). However had to pay 180 AUD per week for a standard bedroom with a shared kitchen and bathroom spaces and utility bills on top of that. For that amount of money I guess I can rent a decent place in the city limits of Colombo(A place where you can buy a boot full of fresh coconuts or mangos for just 10 USD at any time of the year). If the other costs were included (Accommodation, Utility, Heating etc.) the video would've been more informative.
