Hi Stg,

My husband works for CSA, and this is what he says:

It is a centrelink issue whether or not they will grant an exemption, but exemptions seem to be granted in instances of domestic violence, if that is what the social worker has determined in the case.

Centrelink cannot register a case for you, if anything they will cut your FTB. If for some reason exemption is not an option (hypothetically), you can chose not to register a case and go on the base rate of FTB. CSA will not persue him for anything unless you register a case
HTH
