If I were you I'd get more quotes as they cost nothing but if the jobs already done did you agreed on a price before starting?
As a guide:
Excavation should be around $20m3 (+GST). This includes excavation and removal from site and would also include some allowance for rock breaking.
Concrete slab should be around $120/m2 assuming its a pretty standard class of slab and footing design but if its suspended, cantilevered or in a poor site classification this can increase dramatically.

It's an S class raft slab with no slope, no water table, just a retaining wall with a 500 deep * 300 w footing and house footings are 400d * 300w.
Slab size is 341 sp incl patio and entertainment shelter and there are 149.9 l/m of 400*300 footings + 24 l/m of 500*300 footings.
The price was supposed to be under 41,000 for all footings house, retaining wall footings and entertainment shelter footings, standard excavation (excl large area excavation), concrete, steel, other materials (chairs, polythene, tie wire) labour, slab prep and machinery hire (so pretty much everything) as we had two other quotes and they said they could beat them. The excavation of the retaining wall area was ( 27m *1.5m *3m)/2 = 60 cubes of soil.
