Righto,
You take your base rate,
there seem to be a couple of typos here, so you multiply it by 7.32% (eg for CIR) and get a yearly full time rate for your duties.
Divide by 800 for the hourly rate if your a casual
Yes, you divide this by 800, but
casuals also have a 25% increase to cover entitlements that aren't otherwise given.
Like any legal document, read it fully.
Then there is a yearly uniform allowance ($277 odd PA or $5 something per week), 1.8% loading for night ops (+ a transport allowance) and plenty of other small add ons.
