This is just an amateur fishing video, but unlike many of the others it has some really good fishing action interspersed with the usual home video camera work (although I must say it is quite good). If you watch really early on you will see a reef fish being sharked, which has happened to me more times than I can remember and while it may seem a little gross it is the law of nature.
Sharks are a common occurrence on tropical reefs (if I was a shark that is where I would be) and can often be a problem. If you encounter them it is recommended to move to a new patch of reef. The fishing in this video is very typical of bottom bouncing on Northern Australian reefs, but there are still some great fish on show. Enjoy!
