Not sure poopie - I would get DH to check with his rep again. I know our award lets DH have 5 days paternity leave which comes out of his sick leave hours. However sometimes it can be a bit of a discussion to take what you are entitled too. For example we are allowed Carer's leave if our childcare falls through however my boss always tries to get us to take our annual leave instead. She does this to reduce the debt of leave incase we quit as AL gets paid out whereas sick leave does not (for us at least). Different awards have different entitlements.
Perhaps get him to check the facts and then work out what he wants to do. I generally try and approach this stuff knowing my rights and firmly but politely requesting what suits us. Good luck - I have often thought this stuff should not be so hard.
