The Ministry of Transport has told local Aboriginal health services that it is aiming to have air services reinstated by February.

The heads of the Walgett and Bourke Aboriginal medical services met a senior policy officer from the ministry on July 15.

He was in Dubbo as part of investigations into reinstating services that were axed to six western communities in December.

The chief executive officer of the Walgett Aboriginal Medical Service, Christine Corby, says using charter flights has doubled its costs and is not sustainable.

"We're actually selling our charter services to the magistrates and personnel within the shire to offset the extreme costs incurred by the charter airline otherwise we wouldn't be able to sustain what we've been doing since December last year, but it has been very expensive," she said.

She is urging the state and federal governments to help offset the extra costs by providing a subsidy for remote areas while there are no regular air services.

"We may lose services, we may lose specialists coming to our community - I know the magistrates have struggled with their circuits - that is certainly our fear that people may pull out and may not wish to return," she said.
