The North Queensland Helicopter Rescue Service (NQ Rescue) is close to securing $500,000 from the mining industry, already has a pledge of $300,000 in community sponsorship and donations and $200,000 promised by an anonymous sponsor.

But all the funds hinge on the support from the State Government.

NQ Rescue chief executive officer Alex Dorr said the government was the missing link to providing the $1.5million each year needed to maintain the service.

"We're very close to securing two thirds of the funds, but all of these companies and businesses only want to provide the funds if government does its bit too," he said.

"We're calling on government to bridge the gap and fund the other third of the service each year."

The NQ Rescue board submitted an application to the Department of Health this week to secure the funding for a two year trial of the service.

The application had previously been sent to Department of Community Safety, however it was not actioned because the funding arrangements for community helicopters were this month transferred to Queensland Health.

Mr Dorr said he did not expect the government to continue to fund the service, he just wanted help to get the helicopter in the sky.

"We just want a chance to prove the demand for this service because it is so vital to the area," he said.

"Then in two years time the government can sit down and make a decision of whether they can fund it full time."

Member for Mount Isa Betty Kiernan said the Health Minister Paul Lucas had given an undertaking to look into the issue.

The NQ Rescue service has been in limbo since its helicopter was recalled by its owner Sunshine Coast Helicopters in November last year.

The service got approval from the government in February, but so far has not been able to raise the funds necessary to run the helicopter.
