Next month relatives of the MH17 victims will receive an invitation to a private meeting, where they will learn the official cause of their loved ones' death.

The Dutch Safety Board, which is investigating the cause of last year's tragedy, announced on Thursday that it will publish its final report on 13 October.

However a few hours before the publication, the relatives will be told the conclusions of the international team of investigators in a "closed information meeting" in the Netherlands.

Invitations to the information session will be sent out next month, containing the location and time.

DSB spokeswoman Sara Vernooij​ said the DSB could not help overseas relatives travel to the meeting: if they needed financial or other travel assistance it would be up to countries such as Australia and Malaysia.

Malaysia Airlines flight MH17 crashed in Ukraine's east on July 17, 2014, killing all 283 passengers and 15 crew members aboard – including 39 people who called Australia home.

The DSB's report is expected to cover the cause of the crash and will also examine whether the plane should not have been flying over that part of Ukraine during a civil war.

Some details of a draft version of the report have already leaked: in July CNN said the draft report pointed to pro-Russian separatists in Ukraine having shot down the plane using a BUK missile launched from a village under their control.

The DSB's report will be the first of several into the crash – there is also a Joint Investigation Team conducting a criminal investigation into whether any person or group was responsible for the crash.
