    The 4th longest underwater cave in Australia discovered.
    --------------------------------------------------------------------------------

    Description: 7 Nov. 2006.

    Hi There Fellow Explorers!

    Cave Divers Alan Polini and Paul Hosie have just returned from a one week expedition to the Nullarbor Plain exploring and surveying the magnificent Burnabbie Cave. It is not unusual that the cave was extended by 500m and now has over 2,750m (9,000ft) of surveyed passages with a number of leadscontinuing. This makes it the fourth longest underwater cave in Australia so far discovered. What did make this effort unusual was the use of off mounted closed circuit rebreathers to make the 950m (3,000ft) penetration through tenrestrictions to the point where exploration of the cave was progressed using traditional side-mounted open circuit scuba equipment. Most dives conducted were between 3 and 4 hours duration.

    Details of the dives, equipment used and an updated map of the cave will be presented at the upcoming Australian Speleological Federation Conference at Mount Gambier in January 2007.

    Kind Regards,
    Paul Hosie

    Thanks for the post, and link on what the Aussies are doing, that's outstanding! Thought you might want to see the rebreather's their working, with some of the longer penetrations.

    Let's go to Australia....

    Default "BOB" rebreather

    This was awesome! What a great idea and inventive use of technology. See, this is why I love being a cave diver and continually learning from people who are more advanced than I at the sport.

    Yep, the sidemount bailout rebreather is great.
    Forrest is diving one if my memory is still working correctly…

    It seems to have developed out of a need and redundancy.
    Plus, having it under the arm should keep the unit inline with the diver’s lungs so not to have hydrostatic breathing issues.

    My favorite version of this is the D5 by Duncan which is not referenced in this article which is a real shame. http://www.sump4.com/rebreather/

    I am waiting for Dr. Jerome to update his newest dive in France
    172meters (565ft) on his Ouroboros but that is awesome.
    Sub 500ft dives are going to require backup rebreathers; however, that brings all kinds of new issues.
