At the award, today
A month behind
On this one customer, every month, until you raise it.
How I got that
Fair Work Commission annual wage review, as published each year. Compounded on your figure, ex GST.
Two things this does not tell you. Whether your agreement lets you raise the price, and how much notice you owe first. Remembering on 1 July is remembering too late if the contract wants 30 days.
This year also carried a structural change to the lowest award classifications, so if your price is pinned to entry-level labour it moved by more than 4.75%. An estimate about one customer you typed in. Nobody owes you it.
