One can see her point of view but it's very un Australian of her.
Generations of people having been buying up beauty spots for years and turning them into small industrial estates. I think it's called the Australian dream.
Most of my neighbours seem to have sheds far bigger than their houses but according to my realestate agent it's not kitchens and bathrooms that sell houses here but sheds! Oh well choose your battles wisely and good luck with the land grab.
