Hi Giddo,
Lets face it: Builders do their work day in day out, therefore, have an upper hand when dealing with customers.
At completion, they will ask you to sign a document to the effect of saying all work has been completed. If you don't sign, you won't get your copy of Occupancy permit (therefore won't be able to insure the house) nor the keys.
By Victorian standard contract requirement, builders will come back in three months time to fix things under the three month guarantee period. If they won't, you would have the option of claiming the builder's insurance.
Best way to move forward?
If there is any important matter, don't sign up that Completion document.
eg. Gas appliances not working, External doors don't lock, Electrical lights / heater not working...
More minor things can be left until the end of the three month guarantee period. Make sure you won't sign anything at this stage unless things are completed to your satisfaction.
*** Important ***
1. At all time, keep a list of all defects and all your contact with the builder, site supervisor and their tradies, just in case you may need to use them in an insurance claim.
2. At all time, be nice and cool with the builder. He is your best hope for a speedy and cheap completion. A good relationship is always the best road to a happy outcome. A beer at the right time can do the wonder.
All the best
