Using a hi-tech underwater scooter, Mr Vevers is documenting the mysteries of Sydney Harbour and our beaches to create virtual snorkelling tours. A team of six divers from Underwater Earth are currently roaming the depths of Sydney to create the video tours -- which will be posted online in coming months. The clips will highlight the importance of conserving our marine environment. The project is being funded by the Sydney Coastal Councils Group and is the first in what will become a nationwide project. "We're videoing with a special tool we've developed with underwater scooters to give a fish-eye view of that location," Mr Vevers said. "It's to teach people who live in these coastal councils about what lives at their doorstep. Sydney has one of the most impressive marine ecosystems in the world. "The Harbour has got more species of fish than all of the Mediterranean. It has weedy seadragons, sharks, giant cuttlefish and anglerfish -- it's unbelievable." Mr Vevers' project has already discovered new fish in the Harbour.
