The Australia-US alliance has long gone unchallenged. The delegation to free Julian Assange changes that | Emma Shortis

The Australian politicians pushing for Assange's release represents a rare crack in the wall of bipartisan support for the sacrosanct alliance

This week, a delegation of Australian politicians will venture across the Pacific to campaign for the immediate release of Julian Assange. The group, which takes in representatives from the Nationals, Liberals, Greens and independents, will meet with their congressional counterparts and other administration officials to plead Assange's case.

They go armed with a letter signed by more than 60 Australian federal representatives, warning that Assange's extradition to the United States - pursued by both Trump and Biden - would cause outcry" in Australia.
