2 Lot Subdivision

HI All

I have never done or been involved with a small subdivision before.

An opportunity has presented itself for me to cut a house on 1012 square metres of land into a house on 506 square metres and a vacant block on 506 square metres.

I approached a town planning/surveying company today for an estimate of costs and this is what they provided as an estimate.

Council Application Fee          $1,000
Professional Fees for Application     $800
Subdivision and administration fees $2,000
Council Sealing Fee       $300
Council operational Works Fee        $500
Professional Fees for Operational works design survey      $1,000
Engineering Design      $2,000
Electricity application fee     $250
Sewer easement doccuimentation     $250
Registration of Plan and titles fee       $1,500
Council Park Contribution     $5,000
Councis sewer and water headworks     $4,500
Additional Water Connection     $1,000
Sewer Connection      $1,000
Road Widening     $8,000
Concrete Footpath     $3,500     

Total        $32,650 plus GST

Firstly I am shocked at the number of fees and the total cost to subdivide.

My questions are:

1) has anyone done a single block subdivision like this?
2) What is a reasonable amount of time to allow for the process?
3) Are the list of fees identified above normal?
4) Is there any way to mittigate or reduce these fees?
5) Could any of these processes be done by myself for a little work at a fraction of the cost?
6) Do you know anyone that could potentially do it for less?
7) Any advise for a "newbie" to this stratedgy

Thanks in advance

Don
