The cheapest machine can be the furthest away.
Mobilisation is time, route, permits, float availability and uncertainty. Ask where the proposed unit is coming from—not only whether the business services your postcode.
Map the real origin
A provider may operate nationally while an individual asset sits interstate. Request the machine origin and expected travel method for the quoted dates.

Bridge limits, low wires, tight turns, school zones and gate geometry can undo a good highway plan at the site boundary.
Price the return journey
Demobilisation, waiting time, failed access and after-hours delivery can materially change cost. Put the complete movement basis in writing.
