WikiLeaks founder Julian Assange says he's been offered no help from the Australian government in three years, despite claims to the contrary by Foreign Minister Bob Carr.

Assange sought refuge at the Ecuadorian embassy on June 19 last year and has since been granted political asylum by the South American country.

The Australian, who founded thewhistleblower website, is trying to avoid extradition to Sweden to face 2010 allegations of sexual offences in Sweden, which he denies.

He fears that if extradited he could be sent to the US to face espionage charges after WikiLeaks published a trove of classified documents.

Senator Carr last week denied Australia had washed its hands of Assange, telling a Senate estimates hearing the government continued to provide him with a high level of consular assistance.

But Assange said these claims were "remarkable" and "absurd" as he'd had no real contact with Australian officials for some time.

"I have not met ... any consulate, any Australian government official, since 2010," he told ABC television.

"Money that should be spent on actual consular support is simply spent on producing press releases for the foreign minister to make it look like he gives a damn about Australians."

Assange plans to run for the Senate in Victoria at the September 14 federal election, with the WikiLeaks party aiming to field upper house candidates also in NSW and Western Australia.
