I am not sure exactly what I said upon learning that I had received the award for the Healthy Waterways Champion, as it was a big surprise and unexpected honor, but the following is what I was trying to say. Bill giving his Healthy Waters Champion Award speech. "Thank you for this unexpected honor. I am staggered by this award and would like to thank the judges and the award sponsor, Queensland Urban Utilities.

The vibrant Marine Botany group was part of the Botany Department while I was at the University of Queensland, but went into the Centre for Marine Studies after I left. The Botany Department has disappeared and the Centre for Marine Studies has morphed into something quite different, but the spirit of Marine Botany lives on. The Marine Botany crowd has dispersed throughout the world, and throughout Australia, but there are a significant number of Marbots still in Brisbane.

The appeal of iconic creatures has long been used to generate support in the conservation movement. Whales and dolphins in the sea and pandas, gorillas and other apes on land have been and still are conservation icons. WWF still uses the panda in their logo, for example. Icons like birds, particularly raptors, are fairly global. Other icons are rather regional, like Komodo dragons in Indonesia or lemurs in Madagascar.

The story of the naval survey ship Paluma that was cast up into the Botanic Gardens in February 1893 and refloated two weeks later is part of Brisbane lore, and I decided to track down the story about how the Paluma was refloated. I went to the Queensland State Library archive section and was impressed with the beautiful library and helpful staff.

The naming of the city of Darwin is an interesting case of premonition by a sailor. Port Darwin was named by Captain John Wickham in 1839 when the HMS Beagle sailed into Darwin Harbour as part of a survey of Australia's top end. Charles Darwin went on to become one of the most famous men in history, based on his theory of natural selection, the basis of evolutionary thought.

On June 1, I boarded the 'Beaglet', a Natural Resources, Environment, The Arts and Sport (NRETA) boat for a Darwin Harbour field trip. I enjoyed the naming reference to the famous ship 'Beagle' that Charles Darwin sailed around the world, including his famous visit to the Galapagos Islands. The boat skipper was Matt Majid and Julia Fortune was the biologist leading the tour.

The Integration and Application Network recently conducted an international collaboration with people from different organizations and locations in order to develop conceptual diagrams to be used in a booklet on Ecosystem Based Management ( Taking Steps toward Marine and Coastal Ecosystem-Based Management ). The project was supported by the United Nations Environment Programme and we had a short timeline to develop conceptual diagrams before it went to print.

The Swan-Canning River is the estuary adjacent to Perth, the capital of Western Australia, and its seaport, Fremantle at the mouth. The Swan is famous for its iconic black swans and has dolphins that regularly swim up to the foreshore of the central business district of Perth. It supports seagrasses (black swan food), prawns and fish, but has some severe water quality problems.

As part of the National Estuaries Network meeting, we had a field trip to the Peel-Harvey Estuary on 26 May 2011. This site is a globally significant ecological region for the following reasons: 1) Some of the most massive Harmful Algal Blooms (HABs) ever recorded, occurred in the estuary, 2) A major intervention occurred in which a barrier island breach was constructed (the Dawesville cut), and 3) The occurrence of most of the globally significant HAB species.
