Justice search continues for MH17 victims

Four years after 38 Australians died when Malaysia Airlines flight MH17 was shot out of the sky, Australia is still looking for answers.

Foreign Minister Julie Bishop says Tuesday's fourth anniversary of the 2014 disaster was a time to keep pushing.

"We remain resolute in pursuing accountability and seeking justice for the victims and their loved ones," she said.

Ms Bishop has met in the past week with the Australian Federal Police for a briefing on the investigation into the downing of MH17.

"Over 450 AFP have been involved since the tragedy," she said.

"This includes in the search and recovery phase of the operation in July 2014, as well as in an investigative role."

Next week, during a visit to the UK, Ms Bishop will raise the issue with new Foreign Secretary Jeremy Hunt.

"Australia values the UK's strong support, including in the UN Security Council, in calling on Russia to answer for its actions in relation to the tragedy," she said.

"Holding Russia responsible for its role in the downing of MH17 is vital."

Australia and the Netherlands have requested negotiations with Russia over the circumstances behind the attack on the plane.

Ms Bishop will also meet the new Malaysian foreign minister in August to discuss MH17.

The flight was on its way from Amsterdam to Kuala Lumpur when pro-Russian rebels fighting Ukrainians brought it down near Donetsk on July 17, 2014.

The attack killed 298 people, including 38 Australians.
