Between October 6th and December 19th 2009 Dave travelled the length of Australia's Murray River on foot and by kayak, documenting the human, environmental and climatic factors contributing to the decline in health of this once mighty river.

Dave's first encounter with the Murray was three years earlier, when he skated onto the Wellington Ferry in South Australia en route from Perth to Brisbane. That 100 metre crossing was the most peaceful section of his 3618 mile traverse of Australia, and it led to this, his second expedition of over 1000 miles.

From the river's early moments high in the Australian Alps, Dave struggled through heavy blizzards and deep snow before finally settling into his kayak for the final 2350km. Passing along the border of New South Wales and Victoria, the Murray eventually enters South Australia and takes a southerly route to the sea for its final 500km.

Suffice it to say, paddling along a river was a wholly different experience from the road journeys Dave had experience previously, and from then a close love and passion for water developed. Dave is now an Ambassador for the Blue Climate and Oceans Project, and has gone on to paddle and swim other mighty rivers, like the Mississippi and the Missouri.

The final day of Dave's journey brought one of his favourite memories from any expedition. Just a few hundred metres from the ocean Dave was joined by a ... well, just watch the video above.

Bet you're ready to go paddling, now!
