Have you brought this up with your CSA yet? They'll be able to discuss PD's policy on this in detail. I understand you've been in contact with the Building Commission, but I assure you our policy is put in place in the customers best interest to protect you from possible theft. If you are still unsure of the process, I recommend asking your CSA for a potential solution.
My friend is in complete stage with another big 5 builders in Victoria, and they agree with the builder to install the applicances after they get the tenant which they expect 2 - 5 weeks after handover. I'm not sure about the final payment though.
