I'm almost 100% sure that there aren't any left there - but as others have said it could be that a builder still has some blocks available.
All the new estates around that area are $180,000++ for a decent sized block. If there are any H+L packages it will most likely either be for a little cottage on a 300m2 block, or close to the high voltage powerlines around that area that they may be having trouble selling.
Two of my brothers are in Carlisle Park. One is renting, the other built. There are one or two blocks still for sale but they are private re-sales, not through the developer.
You must have bought around the same time as my younger brother. There was only a few blocks left through the developer when they picked their block.
