Liz - if the FAO staff are saying you won't get it, i'd have faith in what they're saying! you can guarantee they've been receiving updates not available to the public within hours of this info coming to light the other day
there is a very real chance that it has restrictions. from what mrsmac is saying, i would assume you'd need to be eligible for FORTNIGHTLY payments, even if it's only a few cents a fortnight. if you look at the table you've linked to, it is the ABSOLUTE limit when the supplements (the $600 per child) cuts out. the threshold for this is significantly higher than the thresholds for fortnightly installments
