Primary Health Care has shut down the clinic and will move the seven doctors to its medical centre in Phillip, despite last-minute pleas from more than 2000 residents to reverse the decision.

Kambah resident Heidi McDonald, who is 31 weeks' pregnant, was the final patient to emerge from Wanniassa Medical Centre last night.

''It's terrible. I don't understand why they're closing it down. It's sad,'' she said.

The company said patients would have access to a wider range of services at Phillip, which is also open for longer hours.

Ms McDonald planned to follow her long-time doctor to Phillip, saying ''I don't have a choice''.

It was a common complaint from the patients who had their final appointments at the Wanniassa Medical Centre.

Patrick Tully was ''not happy'' about the closure, Mark Adamson believed the decision was ''pretty lousy'' and Esther O'Loughlin was ''absolutely disgusted''.

Gail Wright arrived with a bunch of flowers for Jill Brown her GP for more than 20 years. ''I just wanted to show my support and give her my thanks because I didn't really know after today whether I'd actually be able to see her as I normally would,'' Ms Wright said.

''I'm hoping that I will still be able to go into Phillip and make an appointment as usual.

''If not I don't know what I'll do. I've got a small child and trying to find a doctor's surgery that still has open books is not easy.''

Sheridan McVei, her daughter Rachelle and 18-month-old granddaughter Shannon were all patients at the Wanniassa Medical Centre.

The mother and daughter were angry about the closure but the family would travel to Phillip to see their GP. ''But how many times is this going to happen to us?'' Sheridan McVei said. ''Is it because of the shortage of doctors or is it money? We feel it's greed put before people.''

Primary Health Care managing director Dr Edmund Bateman has defended the decision. ''I think no one likes change [but] I think it's change for the better and I think the vast majority of patients, the population of ACT would appreciate what we've done,'' he said recently.

An ACT Legislative Assembly inquiry will be conducted into the closure, with the report due on August 26. The Assembly's health committee wants submissions and will hold a public hearing from 9.30am on Thursday in the Assembly's Committee Room 1.
