It's all in the EBA.
Sunstate EBA 2015 Clause 25.5 (Transition Arrangements)
If you join without 2000hrs aeronautical exp and an ATPL, then the figures in table 25 apply.
If you join with 2000hrs aeronautical exp and an ATPL, then FO's get 65% of the Year 1 Capt rate for the fleet they are on.
I suspect the Eastern EBA has something similar.
Fairwork or AFAP will have the pdf's.
