Just to be clear Woof Woof, you check someone's building licence with the State's building services authority, not Master Builders. Master Builders is just an association, it is not the licensing authority.

Got this guy to do a reblocking job for me the result was far from satisfactory. Threatened legal action then the owner Brett Brock paid a sum of money to get the job redone. This guy is a cowboy hack, no insurance, charges GST with a non registered ABN, don't even think he was qualified as his builders number didn't match Master Builder records. Have reported him to the ATO.
