ftbb is the one for low income member of a couple

and no, it's not true. if you're only receiving ftb and carer ALLOWANCE, there is no need to worry about it. there is no income support in that, it is simply a tax "deduction" for your children, paid to you in fortnightly installments. carer allowance is not included in any work obligations

for income support customer (parenting payment, carer PAYMENT) there may be an obligation, when your youngest child turns six (regardless of what time they start school) to enter into an activitiy agreement (looking for work, study) to receive your payment
