The injury was reported to the Chiropractic Board of Australia, which closed the case without reporting it to the public and allowed the chiropractor to keep practising as long as they undertook education with an ''expert in the field of paediatric chiropractic".

The Sun-Herald has also seen evidence that chiropractors have been entering Sydney hospitals, including neo-natal intensive care wards and surgical wards, to treat patients without the required permission.

NSW Health has warned that any chiropractor working in a hospital without permission could put patients at risk, while the Australian Medical Association NSW says the behaviour is "outrageous".
