The primary family home you live in is not included in the assessment as far as I remember, I also was a homeowner and it never came into it WRT my eligibility for PP. My home was worth $400k - maybe not enough to tip the balance?
I receive appox $650 a f/n in PPS, plus $145 + $130 ish for FTB A and B a fortnight.
You will also qualify for a Pension card, which applies discounts to utilities, telephone, transport, school fees and all sorts of things.
All told, I receive just under $1000 a f/n with 2 children, including $33 rent assistance - which is effected by the CSA assessment. (As is FTB I think)
Hope that helps.
