Arrived at this trig at 0916hrs. Thank God for our friends the Wallabies, as it was their tracks that I followed to the top of Mt Arthur. It looks like it had been a long time since this trig had been visited by humans. The ruins of the old signal station and its convict bricks were a pleasant surprise to find. Those poor souls sure went through hell while they were part of the convict system of centuries past. Good views through the trees of Tasman Island and the associated coastline made the effort of getting to this trig worthwhile. TFTC and cheers OldSaint.
