if you havent already, try mountain equipment in kent streeet sydney, or tom walker at southern cross equipment (also in kent street sydney)
i use the one sport boot (size 11), id dare to say its over kill for what you want it for, (albeit the new model one sport boot is much slimmer than previous models) which is better for technical climbing, the older models are chunky.. and they cost a packet ($1000 +)
ill ask a few people, maybe they have one to fit..
