A Queensland woman has been left fuming after being given only 48 hours' notice to attend a government briefing in Kuala Lumpur on the missing Malaysia Airlines flight MH370.

Danica Weeks's husband Paul was among the 239 people aboard the Boeing 777 when it vanished between Kuala Lumpur and Beijing in March 2014.

The Malaysian Government is today releasing its final report on its investigation into the missing plane, but with two days' notice to travel 6000 kilometres, the Sunshine Coast mum said it was impossible for her to attend.

"I couldn't turn myself around in 48 hours to get there," Ms Weeks said.

"I wanted to be there, to be briefed on the report, I've been waiting to see what is in it."

Ms Weeks said if she had been given more notice of the briefing and that the flights would be paid for, she would have made sure she was there.

She is angry she will miss out on her opportunity to ask questions of the government as to what happened.

"We miss out on the one-to-one question time," she said.

Travel confusion 'a slap in the face'

A representative from a Malaysian support group phoned Ms Weeks early last week and advised there would be a briefing today, but that the families would need to get there at their own expense.

Ms Weeks ruled that out, but was then advised on Thursday that "they were going to pay for our flights."

She was also concerned whether any of the Australian families would make the briefing in time.

"They would be in the same boat as me, with not enough time to organise getting there," she said.

"I'm very angry, that this offer came with only 48 hours to get over there.

"I would have jumped at the chance to ask questions about where my husband is, what happened.

"It is a slap in the face again that we couldn't be there to get the briefing."

Ms Weeks said her children desperately needed answers she was unable to give.

"We need to know, we can't just lose a Boeing," she said.

"This is ludicrous that this can be unsolved.

"I hoped to have answers."

Last goodbye

Ms Weeks waved goodbye to husband Paul as he boarded the flight from Perth to Beijing via Kuala Lumpur on March 8, 2014.

It has become the biggest aviation mystery involving a Boeing 777.

A privately funded search for the missing plane was called off in May.

Ms Weeks and the other families had been waiting for this Malaysian Government report which they hope will shed light on what happened.

But Ms Weeks is not getting her hopes up.

"Once bitten, twice shy, I'm worried they are not going to give much information," she said.

She will have to wait until the media briefing from the Malaysian Government to find out what happened.

"My next step is speaking with the Deputy Prime Minister [Michael McCormack] to ask, 'now that this report is out, where do we go from here?'

"Our loved ones are on that plane, we want answers. Something happened."

Ms Weeks's theory remains something happened to the plane and it had nothing to do with the pilot.

"I believe something happened with the plane and the pilot tried to turn around.

"The plane might have been on autopilot for seven hours before it dropped in the ocean.

"That's my theory, but it is still just such a mystery. I hope one day we will have the answers."
