Andrew grew up on a farming property near Harrow in western Victoria. He started caving while still at school exploring the local volcanic caves located near Byaduk. It was while Andrew was studying Agricultural Science at La Trobe University that he commenced cave diving in the water filled sinkholes and caves of the lower south east of Australia. Andrew went on to become one of Victoria’s first PADI dive instructors, a CDAA cave diving examiner, and one of Australia's most recognised cave divers.

In one of the most significant Australian cave diving discoveries to be made in recent times, Paul Hosie and team have discovered an amazing new cave diving system on the Roe Plains which forms part of the Nullarbor in WA.

A small pool of water in a newly discovered karst feature, led to a small low silty passage which was pushed for 90m and then opened up into a large going passage running at least 800m away from the entrance pool with numerous side passages.

The team explored approximately 1500m of underwater passage in just three days of diving. Plans are underway for a return trip to continue exploration and mapping of this new system.

The team consisted of Paul, Alan Polini, Brian Kakuk (visiting from the Bahamas), Ken Smith, Richard Harris and Grant Pearce.

Update 1st November from Paul Hosie: We just got back from a return trip and have now surveyed 2100m of passage, several leads continuing. I will have a map and updated story on trimixdivers soon.

Update April 15th from Paul Hosie: A further 500m of line was laid in Unnamed Cave on Roe Plains over Easter with Grant Pearce and Chris Edwards making a significant discovery at the end of the B Tunnel.
