When Malaysian Airlines flight MH17 was shot down there were 298 people on board - almost forty of them Australian.
Australian opposition leader Bill Shorten told Amanpour that the Australian government will call for answers to this tragedy in one voice.
"On this matter there is no internal political debate in Australia. We are united in our grief and we are united to get to the bottom of what's happened."
It is a point of union in the otherwise contentious arena of Australian politics.
But the opposition leader has not taken his focus off other issues that impact Australia and its future, particularly climate change.
Prime Minister Tony Abbot's current leadership has led to a unique unwinding of global warming legislation by becoming the first country to repeal a carbon tax law.
It is a decision Shorten vehemently opposed and one he fears will affect people far sooner than they think if no action is taken.
"It's not just for our children and their children. For the current generation climate change is real, and governments will need to act."
