Ive sailed in Broome about 16 years ago in the Easteries 4.7m near a big old jetty there are a few curious sea snakes and old salty crocs have been known to travel down that far. I was young an bullet proof then!
Just came back to Perth after one week in Broome and the wind was too light even for kiters; jellyfish season seemed to be over, last person was stung 14 days ago. Crocs were behind the fence in the park, well fed and lazy :) Loved that warm weather and amazing combination of red soil and blue water...
