We already had the NBN in our quote as well so this is not included in the costs we spent yesterday, we had 1 light in the alfreco included and 1 outside the laundry included but we upgraded the one at the laundry and added an extra flood light at the back of our house (we had a large block so figured we will need it). We also decided not to do the theatre pre wiring, I just added the cost in case others were thinking of it.
You probably already have done this, but if not, sit down with a copy of your plans and mark out everywhere you may need power points and and TV points. Having this plan ready made the appointment go much smoother.
