A Melbourne GP who uses homeopathy and has been treating hundreds of people for controversial condition Lyme disease is fighting for his medical licence after it was alleged he was a risk to patients.

Dr Geoff Kemp, a Camberwell GP for more than 40 years, has been given six weeks to find a doctor who will supervise his work or he may no longer be able to practise.

In September 2015 the Medical Board of Australia imposed conditions on Dr Kemp's licence after a complaint was made about his treatment of a patient he had diagnosed with Lyme disease. The Board indicated that it eventually wished to suspend his licence.

In an interview with Fairfax Media, Dr Kemp said he was being attacked by health authorities who were "anti-Lyme disease" and wanted to shut down doctors who recognise the condition.
