Spoke to someone in the sales office yesterday.
There are only 11 blocks left in the entire estate (apart from blocks that people have bought and are now trying to sell).
The lot numbers are 3322, 4471, 4472, 4556, 4572, 4573, 4657, 4659, 4660, 4705 and 4706.
3322 is only $180k for 1072 m2 and has been on the market for about a year. Weird.
