So, you have signed up with a large building company, such as Metricon or Plantation - what were you thinking?
This document reflects our personal experience of building a new home, and the suggestions are based on that experience. It is not legal advice. The rules differ between states, and the examples here are from Victoria.

Going to the top did not help us either. The senior customer care and building managers did not resolve our complaints. They just delayed things until it was too late for us to act.
If it matters to you, it must be in the contract. What anyone said to you does not count.
Draft regulations in Victoria would change the earlier stages, but still leave only 10% for completion.
So you pay a deposit before any work starts, and you have paid 90% by the end of the fixing stage, while the house is still not finished.
After each payment, we looked at the work left to do. If the company had gone bust at any stage, what we still had to pay would not have been enough to finish the house. We were their line of credit.
The final payment has to be made before handover, because the company will not hand over the keys until you pay. So you have no leverage afterwards. The final payment should really be a month after handover.
