Tasmania Roadtrip - Week 5 - Cape Bruny Walk

The top photo shows 'Swell Rock' which the lighthouse keeper used to measure the wave height/swell and therefore the danger to shipping. Its highest rock sits at 12.8m. If the waves are crashing over the top all of the time that means a 3m swell. If it is never crashing over the top then it is a 1m swell.
