Rex Airlines has gone into a trading halt, with concerns over the future of the regional airline.
Shares will remain on hold until an announcement comes, or until tomorrow when the stock exchange decides otherwise.
The Transport Workers Union says it wants to co-operate to save Rex and thousands of jobs, including those in Mildura.
The union says it worked with Deloitte to get Virgin back in the air and will work just as hard to save Rex.
The halt on trading comes after budget airline, Bonza, went into administration in April.
The trading halt has not had an effect on flights.
The airline flies to and from the local airport each day.
