Hey everyone !! Maybe someone here can help me.

I have a friend who is an Australian citizen and has offered to pay all my expenses in Australia such as food, accommodation etc and can financially support me during my stay as I do not have the funds to do so myself.

Will this be fine? Because I don't have $5000 to go over with. I've tried contacting the Australian embassy but they take forever to respond. So I thought maybe someone here can give me a bit of advice in the meantime. Thanks :)
