Liberal backbencher Craig Kelly has responded to the grieving parents of three children who died when MH17 was shot down in 2014 by saying Russia's involvement should be "looked over" for the sake of good relations.

Mr Kelly has outraged many of his colleagues by declaring "nothing that happens" could bring back the 298 victims of the missile attack.

He was responding to a heartfelt message from Anthony Maslin, the Perth father whose three children were killed on MH17, accusing US President Donald Trump of "kissing the arse" of Russian President Vladimir Putin at their Monday summit.

"Mr Trump, you invented and speak a lot about 'fake news'. But let's try talking about something that's not fake ... let's call them irrefutable facts," Mr Maslin wrote in a public Facebook post.

On Sky News earlier today Mr Kelly responded by saying, "Any father that has lost three kids would be absolutely devastated but the reality is nothing is going to bring those three kids back".

"So what is best for the continued future of the world … and it is best in my opinion that the leader of the USA and the leader of Russia at least have a good talking relationship.

"If that means some of the things that Russia has gotten away with in the past has to be slightly looked over, well I'm sorry that's the price that we have to pay sometimes to have good relations going forward.

"We can't fix things that happened in the past, we've got to make sure that the relationships between Russia and the US going forward are the best they can possibly be."

Opposition Leader Bill Shorten called on Mr Kelly to apologise for his comments.

"I cannot believe he said this. Australians were killed. Children were killed. There are no excuses, ever. Craig Kelly should apologise to the families of the victims," Mr Shorten said on Twitter.

'Russia must be held to account': Julie Bishop

The Australian Government has been scathing in its condemnation of Russia's involvement in the 2014 incident.

Foreign Minister Julie Bishop recently said she considered Russia legally responsible for the downing of the aircraft and should pay compensation to the families of the 38 Australians killed.

"Australia remains committed to seeking justice for the victims of the shooting down of MH17, for which we have attributed state responsibility to Russia," Ms Bishop said in a statement.

"Russia must be held to account. We will continue to work with other nations including the United States to achieve that goal. I will be raising this matter in my meeting with Secretary Pompeo next week."

In a joint statement to mark the anniversary, Ms Bishop and Attorney-General Christian Porter made it clear they held Mr Putin's Russia responsible for the disaster.
