Hello Ms Matherson,

I stumbled upon your post and thought I would pass on the details of a town planning firm you might be interested in (in case you wanted a quote).

http://www.northgroup.com.au – Are primarily land surveyors but they also deal with subdivisions under the following company
http://www.urbanandrural.com.au – Town Planners  that specialise in Subdivisions and Development Consultancy

Thought I'd drop by and give them a mention – Can't hurt to call and ask for a quote.

Best Regards,
M. Knoll
