An Australian senator is calling for the country's opposition leader to throw his support behind a senate inquiry travelling to Australia's asylum seeker detention centre on Papua New Guinea's Manus Island.
The Green senator, Sarah Hanson-Young, has initiated an inquiry to investigate February's violent clashes at the camp that killed an Iranian asylum seeker.
But it's unable to travel to Manus to investigate and interview because the Australian Senate has no jurisdiction in Papua New Guinea.
Sarah Hanson Young says that can be overcome, and is being used as an excuse by the government of Prime Minister Tony Abbott.
"It won't go away. A young man was killed, many injured, Australia's international reputation is in tatters and it's time for Bill Shorten to come out and back a full, frank parliamentary inquiry which has to include the committee visiting Manus Island."
