Treasurer Josh Frydenberg and backbencher Gladys Liu have conceded that controversial Chinese-language signs they put up at voting booths on the day of the federal election had the wrong translations.

In filings made in the Federal Court on Wednesday, Mr Frydenberg and Ms Liu said that the signs “intended the following translation: to make your vote count, put a one next to the Liberal Party candidate”. But the signs, which were in Australian Electoral Commission colours, told voters that "the correct voting method" was to put a one next to the Liberal candidate.

Mr Frydenberg's election is being challenged by Oliver Yates, who ran against him in the seat of Kooyong. Mr Frydenberg won the seat easily, winning 11,289 more votes than his nearest competitor.

Ms Liu’s tight election win is being challenged by a voter in the seat of Chisholm, Vanessa Garbett, who has previously been involved in the union movement.
