DP earns approx $75k a year before tax. I get approx $7.5k a year FTB. We rent in Sydney (3brm house $550 a week) and currently any savings we have goes to IVF. We could save more, but at the moment we are just happy getting buy.
I don't really know what we spend honestly, but we aren't in any debt and I can afford to buy some brand name clothes for my kids, and we go out for breakky or dinner once or twice a fortnight. Eventually we will have to buckle down but I'm studying and we know that it won't be too long before I'm working again and then we will do what we've always done - live off DPs income and save mine.
