Wow, thanks for all the replies.

Misty, thanks, I will certainly keep you updated.

Raddles, thanks for the links and you have raised  a point I forgot to mention. About three years ago, the plans for the subdivision were submited with the shire. Residents were able to object to them etc. My folks did object, but of course the subdivision stll went through. The plans showed a plan for subdivision of the 4 farms all in a line ie may parents, their neighbours etc.  About a year ago, the dev. company offered my folks X amount of money for their property (I believed they also offered the other neighbours as well who all refused). I wonder if they are trying it on like you said L.A. and scaring them into selling?

cheers
