accruals on unpaid leave

I have a full time employee who is really unwell and does not have much of there accrued leave left, so over the last few weeks i have paid 10 hrs A/L and the balance as unpaid leave per week to stretch it our for her.  During this time I have been giving the full accrual of A/l and P/l, which is fine, but i have just become aware that I shouldn't be giving the full accrual and it should be just on their paid A/l hours.....  Can someone please clarify fo rme if the latter is the way to go.

Also, public holiday coming up this week, if she is still only getting 10hrs A/l or whatever is left in P/l and the balance as unpaid leave, does she get the public holiday paid...I did read no, but if someone can clarify that would be great.

Lastly, i havn't setup unpaid leave in MYOB, but this is probably something i should do?

Thank you,
