Bishop sickened by MH17 rebels footage

Foreign Minister Julie Bishop is sickened by footage of Russian-backed rebels ransacking luggage of passengers aboard the crashed Malaysia Airlines flight MH17.

Ms Bishop said she couldn't verify the authenticity of the video published by News Corp Australia.

"It is sickening to watch and 12 months on from the downing of MH17 it is deeply concerning that this footage has emerged now," Ms Bishop told the Nine Network.

Ms Bishop said it had been a tough year for grieving families and it would be an emotional day ahead.

"Their grief is inconsolable and the burden of grieving and then seeing this footage will be almost too much to bear," she said.

The disaster killed 298 people, including 39 who called Australia home.

An estimated 200 of their family members will attend a commemoration at Parliament House in Canberra on Friday.

Ms Bishop has flagged a second investigation report into the tragedy will be released in October.

The next step was establishing an international criminal tribunal, but Ms Bishop acknowledged it would be tough to get it approved by the United Nations Security Council.
