The Captain James Cook Memorial was built by the Commonwealth Government to commemorate the Bicentenary of Captain James Cook's first sighting of the east coast of Australia. The memorial includes a water jet located in the central basin and a skeleton globe sculpture at Regatta Point showing the paths of Cook's expeditions. On 25 April 1970, Queen Elizabeth II officially inaugurated the memorial. When running both pumps simultaneously, the main jet throws approximately six tons of water into the air at any instant, reaching a maximum height of 147 metres. Alternatively the jet can be run on a single pump reaching a lower height of 110 metres. During special occasions it can be illuminated, often with coloured lights.
