Potential move to Sydney

[Gbondy]

Hello.

My husband has been offered a family relocation to Sydney on Sponsored Visa. 

Before progressing more with his company, i would like to get my facts straight money wise to make sure the move is within our budgets.

I have heard that Sydney is quite expensive, husband will be on roughly $120,000 but not sure what mine will be.

We have 2 children (8 and 12).

Please could someone give me a rough guide on monthly costs (Bills, Food) and also not sure where to even look regarding schools?

Still early days but would appreciate any help or advice.

Thanks
