Now for labour it would take 2 to 3 days to construct with two carpenters. I would expect a labour charge of around $120 per hour plus GST for two chippies. Slightly less if one is an apprentice or TA. It took me 2 days on my own, but I worked straight through breaks and I worked longer. So labour could be some where around $1920 to $2880 excluding GST.
It will cost more if you are using hardwood in terms of labour. It is harder to work with and requires a lot of pre-drilling. It may well take 4 days if the timber is really hard.
However somewhere around $3900 would be a practical starting point. Three quotes is definitely best. You may find with work being a little on the lean side at present that people will work for a lot less just to keep the bills paid.
Best of luck.

Unless you are doing the slightly off ground deck yourself (in which case the labour costs are ZERO), then it's cheaper to pay a concreter to form up and lay a slab of concrete.
I had a quote in February of $1260 to form up and lay a 3.8m x 3.3m slab with a 380mm lip at the bottom end (my land has a slight slope on it.)
If you are doing a DIYS slightly off ground deck , you still need to do a solid concrete footing onto which either the tripod will be parked or you'll bolt the pier , unless you go for a concrete pier which means even more formwork and reinforcing.... add several hundred dollars to materials.
I'm starting to think that maybe a concrete slab surrounding but isolated from a 1 sqm x 0.5m deep concrete footing may be the best way to go for the floor of a ROR shed.
So long as it's shaded from direct sun , the concrete not be a thermal issue.
Plus , termites aren't very keen on concrete.
