A German tourist died after the vehicle she was a passenger in ran off a gravel road and over a steep embankment in the Leven Canyon area.

The driver, also a tourist, escaped from the vehicle with non-life-threatening injuries.

Police also warned Falls Festival patrons that there would be a heavy police presence in the Marion Bay area, with the start of the music festival tomorrow.

``It is important to remind all drivers, especially those less experienced, of the need for safe driving and patience as traffic delays will be expected,'' Inspector Darren Hopkins, of Northern District Support Services, said.

``Police will have strong presence up to the conclusion of the event.''
