THE Chongqing-born son of a Taiwanese diplomat, Mr Tchen Tsebin, will make Asian-Australian history on Saturday when his name appears on the Victorian Senate ballot paper as a Liberal Party candidate in the Australian federal election. Mr Tchen, who settled in Australia at the age of 16 after leaving China when he was two and spending his youth in the Middle East, Vietnam, Taiwan and Tahiti where his father was posted, is believed to be the first Asian migrant nominated by a major political party for a seat in the Australian parliament. As required by Public Service rules, he resigned from his job as a Victorian Ministry of Planning town planner to contest what is widely seen as an unwinnable contest - the fourth position on the six member Liberal/National joint Senate ticket. Mr Tchen, who was educated in Canberra and Sydney and is known here as Bin Tchen, refuses to concede his task is impossible - three of the six Victorian Senate posts usually go to the winning party, two to the loser and one to the Democrats under the proportional voting system, but if the Liberal-National coalition wins office with a swing of more than five per cent, he could win a fourth seat for them. Mr Tchen, 52, told The South China Morning Post he stood for parliament because Australian politics did not reflect the country's multi-cultural population. ''I believe there is a lack of confidence on the part of the ethnic communities in their ability to get representation in the mainstream,'' he said. ''They lack knowledge about the political process. Maybe it seems much harder than it is. ''Also there may be some reluctance on the part of the political parties as to whether someone from a non-English speaking background has the ability to enhance their performance in the campaign.'' Mr Tchen, whose wife, Pauline, was born in Hongkong, said that in 36 years in Australia he had had no ''particularly noticeable'' experience of racism. He said he would campaign for closer ties with Taiwan if they would benefit Australia, but also backed closer effective links with China. Mr Tchen said that he did not have difficulty defending the coalition's immigration policy, although it advocated a cut in migrant numbers, because he believed those numbers should be tied to the state of the economy.
