Police say the family of a Queensland officer who was shot in the face have decided to turn off his life support today.

Senior Constable Damian Leeding, 35, has been in an induced coma in hospital since being shot during an armed hold-up on Sunday night.

It is understood three people armed with guns had been threatening staff and customers at the Pacific Pines tavern.

Senior Constable Leeding and another officer responded to a triple-0 call from one of the hostages being held inside.

Shortly afterwards, the father of two was shot outside.

He is in the Gold Coast Hospital in a critical condition.

Last night, it was revealed his family have decided to switch off life support, based on medical advice.

Queensland Police Union (QPU) president Ian Leavers says he has met with Senior Constable Leeding's wife, who is also a police officer.

"Very difficult decision that no-one should ever have to make for their loved one. who simply goes to work and ends up like Damian is at this point in time," he said.

"We couldn't imagine the pain unless we've gone through it - very difficult, very tough decision, but what can you say.

"At this point words cannot describe the heartache and heartbreak that we're all feeling.

"This has affected police, not only in the Gold Coast area, but all across Queensland and Australia."

Police say they will continue to help Senior Constable Leeding's family, friends and colleagues.

"Our thoughts are very much with his family, friends and Damian's Coomera CIB colleagues," a statement from the Queensland Police Service said last night.

"We would like to thank everyone who has been involved in the care of DSC [Detective Senior Constable] Leeding, including the QAS [Queensland Ambulance Service] officers, nursing and medical staff at the Gold Coast Hospital."

Two men aged 37 and 38 and a 37-year-old woman were remanded in custody after appearing in court on Tuesday on charges, including attempted murder and deprivation of liberty.

The attack on Senior Constable Leeding has prompted calls for a dedicated armed-robbery investigation team to be set up on the Gold Coast.

Donations

Meanwhile, a special bank account is being set up for the family of Senior Constable Leeding.

Police Commissioner Bob Atkinson says the incident has prompted an outpouring of grief from the wider community.

He says the Queensland Police Union will set up an account for those wishing to make donations to Constable Leeding's wife and two young children.

"The details of that aren't known yet but we'll obviously make that available," he said.

"The other way which is another option is to donate to Police Legacy and the third way, if people are unable to make a donation - and we're not asking them to - we're just putting the offer out there in response to people's requests as to how they can help - the third way is a symbolic way and that is to wear a blue ribbon."
