Can you help me choose a locality in Melbourne?

Hi,

I am in moving to Melbourne in few months as a migrant in the hope to find a suitable job. I have never visited Melbourne before and am single.

Can you suggest a locality that offers affordable stay. I prefer to live in a quite place as I presume most parts of the city is safe. I should also be able to move around easily to be able to visit companies.

An approximate indication of house/apartment rents would help me in my preparations.

Thanks.
