- The History
- 34 km Big Swim Derwent River from New Norfolk Bridge to Tasman Bridge, Hobart.
- Other swims on the Derwent River
History There have been swimming events of various types and distances on the Derwent River since 1803 when Hobart was settled. These have been conducted by many swim clubs and individual organisations, namely regatta associations.
In Tasmania, the long-distance swims, the swimming marathons, were pioneered by Chris Guesdon in 1961
The Australian Long-Distance Swimming Federation was formed in 1973 in Hobart to facilitate recognition of the new sport as this was not forthcoming from the pool orientated national body. The foundation members and subsequent office bearers were Chris Guesdon President, Deputy President Dick Campion, Secretary Sue Guesdon, John Koorey Executive Member
The body changed its name in 1980 to the Australian Marathon Swimming Federation. John Koorey later became the President and the Australian Championships moved to Sydney, New South Wales. The Australian Marathon Swimming Federation ran the national open water swimming titles until FINA and therefore Australian Swimming Inc. took over open water in 1986.
The first Australian Swimming Inc, Open Water Swimming Committee was set up in 1988. Guesdon then became the Secretary of Australian Swimming’s National Open Water Swimming Committee and Koorey and Campion moved across as committee members of that national body. From this beginning the movement of open water swimming was grabbing a foothold across the country. Health, fitness and elite competition programmes in open water and rather than swimming pools, were flourishing and here to stay.
In 2018 there were as many individuals swimming in hundreds of separate events in Australia in open water competitions as there were members in pool swimming clubs. These numbers didn’t include those plunging into the open water on their own as an activity for health and fitness reasons. In subsequent years many other nations and individual hallmark events followed the Australian lead and national and world bodies were formed

Other Derwent River Swims and Courses
There are numerous courses swum on this great river Derwent, across, up and down the river. There are three bridges used as starting and finishing lines. The history on the Derwent swims is therefore not restricted to one course and a few swimmers. There are many swimmers and courses. Since the beginning in 1973 when the Australian Long-Distance Swimming Federation was formed, 46 swimmers have competed in the various races in the Derwent at marathon distance. The body was run by volunteers who in fact underwrote the sanctioned events both financially and with manpower. The organisers provided accommodation, boats, watercraft & personnel. A number of swims have commenced and continue in the Derwent River, but most are not of marathon distance. There are other swims across the river of about 2k-5k. One of which is the Trans Derwent Royal Hobart Regatta Race 1.5k which is the second oldest continuously run race in Australia. Other distances across the river reach 5k. The 15k event from Kingston Beach to Constitution Dock Hobart. Other swims have commenced in Hobart and finished in Kingston and/or in the opposite direction. One of our swims the Kingston to Hobart 15km was the Australian Championship race.
Top Australian and New Zealand competitors included, record holder for the fastest triple crossing of the English Channel, Philip Rush NZ. Australia’s John Koorey: 1st Australian man and 2nd Aus. swimmer to cross the English Channel. Another winner was Graham Bruce, English Channel conqueror & member of the 1983-84 & 1996 Australian Open Water Teams The first to complete the swim on that course was in the opposite direction from Hobart to Kingston. 15km distance was swum by Chris Guesdon in 1981.
