The poll of 1000 voters was conducted at the end of last month by UMR Research, the company the Labor Party uses for its internal polling.

Mr Assange, who is still under house arrest in London fighting moves to extradite him to Sweden on sexual assault allegations, signalled in March that he wanted to run for the Senate at the next federal election.
