Scientists plot course of great white shark.

A great white shark tagged in South Australian waters three months ago has shown up off the northern coast of Western Australia.

CSIRO scientists placed a satellite tracking device on the shark in waters near Port Lincoln.
Recent data showed the female great white, known as Columba, was about 100 kilometres north-west of Exmouth, at a depth of about 600 metres.

CSIRO research scientist Barry Bruce says the information is important for two reasons.
"We're trying to understand what draws sharks to certain areas at certain times, what pathways they use to move between these certain areas and use that information to minimise the risk that we pose to sharks," he said.

"But also see if we can use that information to minimise the risk that sharks pose to us."
Mr Bruce says it is the first time such a long journey has been successfully tracked by satellite.
"They must be making these journeys for particular reasons, so it's exciting for us to be able to plot its course as it goes up the coast and it's found this area," he said.

"Now it's been up there for the last two-and-a-half weeks and we're currently in the process of contacting various colleagues that work in the area just to see what on earth would attract a white shark to deep water off this particular area."
