Now we can find out where the sharks are

SHARK watchers are now able to observe the last known position of up to eight sharks so far tagged by the Department of Primary Industries off Ballina.

Eight sharks off the Northern Rivers coast can now be tracked on a regular basis.

The map is available at http://www.dpi.nsw.gov.au/fisheries/info/sharks/tips-to-reduce-your-risk-of-shark-attack/north-coast-shark-tracking

It shows the last known position of eight sharks, and is expected to be shortly uploaded with at least four more tagged so far this week in the program.

But the map falls short of real-time tracking, because the satellite tags planted into the shark's dorsal fins can only transmit when the shark breaches the surface of the ocean.

Sharks have no need to breach, however, so each transmission can be separated by days, weeks or even months.
