There's a real likelihood GP clinics will close, as the financial squeeze goes on.

A survey by the General Practice Owners Association has found 83 percent of respondents are worried about their long-term viability.

College of General Practitioners President Samantha Murton says practices with several branches will have to reduce sites.

"There will be practices that do close because people who have been putting out the best that they can for service will say - we can't afford to do this extra. So we're retrenching back and just doing the minimum that we can possibly do."
