Up to 600 pro-Tibet protesters were expected to attend the relay, along with between 2,000 and 10,000 Chinese supporters. Taking note of the high number of Chinese supporters, Ted Quinlan, head of the Canberra torch relay committee, said: "We didn't expect this reaction from the Chinese community. It is obviously a well-coordinated plan to take the day by weight of numbers. But we have assurances that it will be done peacefully.". Also, Australia's ACT Chief Minister, Jon Stanhope confirmed that the Chinese embassy was closely involve to ensure that "pro-China demonstrators vastly outnumbered Tibetan activists." Australian freestyle swimmer and five-time Olympic gold medalist Ian Thorpe ended the Australian leg of the torch relay April 24, 2008, touching the flame to light a cauldron after a run that was only marginally marked by protests. People demonstrated both for China and for Tibet. At least five people were arrested during the torch relay. Police said "the five were arrested for interfering with the event under special powers enacted in the wake of massive protests against Chinese policy toward Tibet." At one point, groups of Chinese students surrounded and intimidated pro-Tibet protesters. One person had to be pulled aboard a police launch when a group of pro-Chinese students looked like they might force him into the lake.
