Not sure in vic, but in SA there is an award rate as a brickies labourer. Definitely a different amount to a bricklayer who has completed a 4 year apprenticeship.you should be able to look up the award rate. Technically as a subcontractor you can charge what you like, but normally you would have an agreed amount prior to starting. As in a bricklayer might like to be payed $2 a brick, but really he will only get work if he charges $1 per brick because that's the agreed rate.

Does that make sense? It's been a looooonnnngggg day!
