Virgin plane makes emergency landing at Mildura Airport

Passengers on board a flight forced to make an emergency landing in regional Victoria say they were told to brace for a bumpy landing.

The Virgin Airlines 737, carrying 91 passengers, was travelling from Brisbane but was unable to land in Adelaide due to heavy fog.

It was diverted to Mildura, but encountered similar issues.

After two aborted attempts to land, the crew made an emergency declaration, and emergency services were sent to the tarmac.

The plane landed safely, much to the relief of those on board who were told to brace on touch down.

One passenger told 7News: "When we made a successful landing, the Virgin air hostesses were saying 'brace now, brace now'."

Another shaken passenger said it was a 'nerve-wracking' situation.

"We were pretty much called to go into brace position because we were going in for a landing," he said. "The cabin crew at the back were like 'heads down, stay low'."

All 85 passengers and six crew members disembarked safely shortly after 10am.

A Virgin Australia spokesman told AAP the request for priority landing was made because the plane was running low on fuel, and because of the difficult weather conditions.

All passengers would be transferred to Adelaide by Tuesday evening, the spokesman said.

A Mildura Airport spokesman said a Qantas flight was also diverted to Mildura on Tuesday and landed without incident.

The Australian Transport Safety Bureau says it is collecting information about the incident, and may conduct a formal investigation.
