Just about to buy a house, I've been quoted $1000yr for the house insurance and $500 extra for contents insurance up to $50,000.

I was wanting to kinda do this as a flat thing, so if the place burns down we all get $12k each towards our stuff, or if we get robbed we can just claim on the stuff that was stolen 

q1) Does home and contents cover all the contents in my house? or just the stuff I can personally prove I own? Would it also cover my flatmates / friends / families stuff?

q2) If not, is there a good package / provider that does provide this?

q3) What sort of insurance do you use and what are your thoughts on it?

Thanks!
