South Australia's National Parks Guide
SOUTH AUSTRALIA’S NATIONAL PARKS GUIDE Explore some of South Australia’s most inspirational places INTRODUCTION Generations of South Australians and visitors to our State cherish memories of our national parks. From camping with family and friends in the iconic Flinders Ranges, picnicking at popular Adelaide parks such as Belair National Park or fishing and swimming along our long and winding coast, there are countless opportunities to connect with nature and discover landscapes of both natural and cultural significance. South Australia’s parks make an important contribution to the economic development of the State through nature- based tourism, recreation and biodiversity. They also contribute to the healthy lifestyles we as a community enjoy and they are cornerstones of our efforts to conserve South Australia’s native plants and animals. In recognition of the importance of our parks, the Department of Environment, Water and Natural Resources is enhancing experiences for visitors, such as improving park infrastructure and providing opportunities for volunteers to contribute to conservation efforts. It is important that we all continue to celebrate South Australia’s parks and recognise the contribution that people make to conservation. Helping achieve that vision is the fun part – all you need to do is visit a park and take advantage of all it has to offer.

Dr Craig Challen SC OAM
Dr Craig Challen SC OAM Australian of the Year 2019, Thai Cave Rescue Diver, Aviator and Keynote Speaker Dr Craig Challen was named Australian of the Year 2019 in recognition of his work to rescue 12 young soccer players and their coach from a flooded Thai cave in Chiang Rai, Thailand in July 2018. Craig is in high demand as a keynote speaker. He presents alone or in partnership with fellow cave rescue diver Dr Richard Harris. An internationally recognised diver, a former vet, CEO and keen aviator, Craig is able to tailor his presentations to suit the audience and is available for question and answer sessions. More about Dr Craig Challen: Craig was about to go on a caving holiday in the Nullarbor Plains, when he was called to help the rescue mission based on his technical expertise. Although he initially thought the rescue would be too difficult to accomplish, he played a leading role in the successful mission. Working 10 to 12 hours a day in extremely dangerous conditions, he repeatedly risked his life as the children were swum, one by one, through the dark and narrow flooded caves. Craig was awarded the Star of Courage for his unwavering and selfless bravery. In 2019 he was recognised as Australian of the Year for Western Australia. One of Australia’s leading technical divers, Craig is a member of the Wet Mules, a diving group that takes on some of the world’s deepest caves. After commencing cave diving in the 1990s he was an early adopter of closed-circuit mixed gas rebreathers. -

The Environmental, Social and Human Health Importance of the Aquifers and Wetlands of the Lower South East of South Australia An
The environmental, social and human health importance of the aquifers and wetlands of the Lower South East of South Australia and SW Victoria and the increasing threats to their existence. My submission to the Senate Select Committee on Unconventional Gas Mining March 2016 I am Marcia Lorenz B.A. Grad. Dip. Ed. Admin., a retired school teacher. I only discovered the attractions of the South East when I came to Beachport 12 years ago. I am a volunteer at the Millicent High School where I support the Aboriginal children in their work with their culture and the environment. I am also a volunteer with other environmental groups in the region. My submission concerns the likely detrimental effect of unconventional gas extraction (“fracking”) on the aquifers and wetlands of the South East of South Australia and therefore on the myriad of species, both flora and fauna that constitute wetland habitats. 1 HISTORY Historically, post white settlement, wetlands were viewed as wastelands with no thought being given to the natural environment and the diversity of species they contained. Economics was the driving force. It would be wonderful if we could say that times have changed and politically there is the realisation that in order for humans to exist, the natural environment must be taken into consideration. After all we now have knowledge that wasn’t available to the ordinary person in the early days of settlement. Post European settlement change in land use has significantly altered the landscape of the South East resulting in the loss of many areas of wetland habitat with <6% of the original wetland extent now remaining.1 An estimated 2,515 km. -
