Depth, diameter and cage position, verified while the hole is still open.
Piers appear on Oran Park lots where the footing has to reach through reshaped ground to something the engineer will rely on. Given the town sits on land that was a racing circuit until 2010, that is worth taking seriously: your soil report and engineering say what depth is required, and depth is the one dimension nobody can confirm after concrete.

Under an hour on a standard lot, longer where there are many piers or the site is awkward to move around.
The measured figure sits beside the required figure in the report. The remedy is for the builder and their engineer to propose.
No. We record against the engineering; certification is an engineer's function and the report says where one is needed.
It makes the soil report more worth reading than usual. Reshaped ground is exactly why an engineer may specify piers, and why the specified depth matters.
A day is enough. Piers are frequently bored and filled inside two days.
Your lot's engineering with pier depths, diameters and positions, plus the soil report if you have it.
