G'Day JR,

I personally started by visiting my local council. ( Inform them that you wish to build on your land)     
I've built a house starting from that point. Your question on charges etc, every council has differing fees and charges.

 I employed Braddon Building Surveying company who dealt with all my paper work, who then submitted it all to council They carried out all inspections re building progression and then did final assessment for sign off (occupancy certificate) etc 

I wish you all the best and do hope this will help you make a start.

PS you have a lot of homework to do. Get a least 3-4 written quotes from persons drawing your plans. Written quotes for all other workers Builders etc Make sure they have insurance "never assume anything" 
Keep a strict diary of all your costings, quotes etc.   

Cheers
