After Mortgages, rates, land tax, bills, etc, We are left with about $500 a fortnight (give or take $100 depending Army reserve pay), About $300 is dedicated to food, nappies, toileteries etc, Which leaves $200 a fortnight for anything else, coffee, clothing, school stuff, takeaway, extra bread and milk, etc. It doesn't go very far in a family of 6. Thankfully fuel is already paid as the cars a salary sacrificed, or we'd be really in the red, because we have two cars and my big people mover uses alot of fuel.
