BG (or anyone!!)

When I am on maternity leave I am planning on claiming the Govt Paid Parental Leave payments, but leaving it until the end of my leave because with my Employers Maternity Leave, My Annual Leave and My Long Service Leave there will only be 14 weeks remaining that are unpaid.

So I figure if I claim the GPPL scheme for the last 4 weeks of my other entitlements + the last 14 unpaid weeks (18 weeks in total) I will be better off as this will mean for 14 of those 18 weeks the tax withheld will be less as there is no other income to push the tax withheld up - does that make sense?

Am I on the right track?

TIA
