## Endurance events
### Crossing the Ditch

As Cas & Jonesy they became the first people to cross the Tasman Sea from Australia to New Zealand in a kayak. They set off from Forster, New South Wales on 13 November 2007 and arrived at Ngamotu Beach in New Plymouth, New Zealand on 13 January 2008, taking a total of 60 days, 20 hours and 50 minutes for crossing.
Cas and Jonesy travelled in a double kayak named Lot 41, custom designed by Rob Feloy. They transmitted podcasts and photographs during the trip.

### Crossing the Ice

On 26 January 2012, Cas & Jonesy succeeded in skiing from the edge of Antarctica to the South Pole and back without assistance. It took 89 days and 2275 km of skiing, in what was the longest unsupported polar expedition of all time (the pair also finished along with Norwegian adventurer Aleksander Gamme, who had waited for them). Pulling everything they needed on a sled behind them and facing temperatures as low as – 40 C, they endured frostbite, crevasses, equipment failure and food deprivation.
The pair had almost no skiing experience before their expedition and spent months researching and consulting with experts from all over the world. They trained in the Arctic and in New Zealand, acclimatizing themselves to the extreme cold they would experience during the adventure. The Australian adventurers are the youngest team to ever reach the South Pole.

### Okefenokee Swamp

In 2013, Cas and Jonesy completed the world's first on-foot segment crossing of the Okefenokee swamp, the largest blackwater swamp in North America. The pair were filming a pilot for National Geographic titled "Surviving Wild America", in which they retraced a 9-mile trail that had not been used in 40 years. They slept in hammocks above the swamp, travelled in blow up rafts and experienced numerous encounters with alligators, cotton mouth snakes and black bears

### Bass Strait

The pair completed an unsupported Eastern route crossing in 9 days, travelling 340 km by kayak in 2006. The Bass Strait is the sea strait which separates Tasmania from the Australian mainland.

### Murray River

Cas & Jonesy completed the world's first traverse of the Murray River, Australia's longest river, by kayak. They spent 49 days in 2001 and 2002 travelling a total of 2,560 km, raising $9,500 for the annual fundraiser Kayak for Kids.

## Media

Published in January 2010, the book Crossing the Ditch tells the story of Cas and Jonesy's adventure across the Tasman, paddling more than 2000 km kayak from Australia to New Zealand.
Extreme South was written by Castrission following the couple's South Pole excursion and was published in July 2012.
In the documentary Crossing The Ditch (aka 62 Days at Sea), Jones uses footage recorded during Cas and Jonesy's crossing of the Tasman Sea to tell the story of their kayak journey from Australia to New Zealand. The documentary features interviews from both adventurers.
In his second documentary, Crossing the Ice, Jones uses recorded footage and interviews to tell the story of the pair's journey over 1,140 km to the South Pole and back again, and the quest to become the first humans to achieve the feat unassisted.
