I just applied yesterday -
I think the below should apply to you - this is off the parental leave claim form that I completed online:

worked for at least 10 of the 13 months prior to the birth or adoption of your child, and
worked for at least 330 hours in that 10 month period (just over one day a week) with no more than an eight week gap between two consecutive working days.

It seemed a pretty low work requirement in my opinion - but regardless, it would incorporate any leave you had for holidays I would hope? I went to Centrelink yesterday for the first time ever. OMG what a waste of time that was.

It also says something on the claim form about going overdue - they don't penalise you for being overdue. Go online and have a look at the claim form as I remember seeing something about that too.
