there is a wait period but from experience if u can prove leaving was for health reasons then the wait period doesnt apply.if it was documented that ur dh was stressed due to work when he went to hospital with chest pains then u may b safe.either way,ring centrelink asap because if they approve payment then they use the phone contact as start date and u may get back pay.they will ask u to also go into office if approved and do paperwork so b prepared if u need to arrange seperation certificate etc.good luck.
