I will be there in e few weeks but i don't have any acquaintances who live there. Is there someone who could provide me with some guidance in the airport. I'm dreaded that i wouldn't find out where to go after my plane lands. What is the most sensible option (economic, safe) where one can stay until finding the permanent accomodation?

Depending on the amount of money you have to spend, you could book into a hotel (look on wotif), hostel (hostelworld), Airbnb, couchsurfing or a short term lease (look on gumtree).

When you arrive at the airport you can get a taxi (there's a calculator on the airport website to tell you how much it will cost) or you can take the skybus for about $16 one way.

Thanks for the resources you have've provided.

Housing price in Melbourne is, on average, 10.8 times the anual median income. I'm probably moving there once I get my bachelor's in Electromechanical Engineering, then I'm planning to study a Master at UniMelb
