Hey Alec,
I would definitely get a second opinion and appeal. I know at least 2 other guys that have been told they dont meet the minimum eye standard. Apparently a new guy at AVMED is not letting people through if they dont meet the prescribed standard even if the optometrist says they are suitable for pilot. The optometrist in Perth resubmitted the paper work but wont hear anything until the new year. Although I dont know your situation I would look into it.
