Looks like it's barely taken 24 hours before for another option to come forward - this time a block that fit both the size and budget requirements!
It took a few days before we could get out there to investigate, but the short version is the location is fantastic!
Just a hundred meters to the east is Malcolm creek, and the walking/running track that goes basically the whole way around the Highlands area. And if it's groceries or coffee anyone's after, that's just a 500 meter walk across the creek - so it's not like it's a major thoroughfare for traffic.
Oh yeah - and our nearest current neighbours have already found a flagpole.
