Ken Wyatt, 57, took the seat of Hasluck in Western Australia for the centre-right Liberal Party.

Neither the Liberals nor the governing Labor Party gained enough seats at last week's election for a majority.

As counting closed, Mr Wyatt declared victory with a majority of nearly 1,000 votes over his rival from the centre-left Labor Party, with fewer than 1,000 votes still to be counted.

Mr Wyatt is the first Aboriginal man elected to the House of Representatives but two other indigenous Australians have served as senators in the upper house of parliament.
