I paid $35,000 for a large main street plot with a house and a 360 sqm former supermarket and a 60sqm shop and two big sheds.
I paid around $15,000 for 1000 sqm land on a quiet street of Collarenbri, which has much more facilities (incl a public olympic swimming pool and a school which the Feds spent $5M renovating.
