I guess most would say National Ocean and Moonah were pretty amazing sites, but I have not played Moonah so I cant attest to that effort.
Not sure what the site of the Capital in Melbourne is like as I am not a high roller and so no chance of getting on. Its only a stones throw from Kingston Heath, but perhaps it is swamp - I don't know.
There was also the reno work he did at Royal Adelaide and Lake Karrinyup, both decent sites, that have had to be dug up and redone.
Don't know much about the non-Aussie work.
