Joshua Tam, 22, became separated from his group of about 15 friends at the Glenworth Valley festival in December when he had an adverse reaction to drugs and was taken to hospital.

His death is one of six drug-related fatalities at music festivals being investigated by the coroner.

The court today heard medical services company EMS contracted only one doctor to work at the event, which was attended by about 11,000 people.

Dr Krishna Sura told the inquest he expressed reservations about the arrangements to EMS director Mike Hammond prior to the event.

He said he was not equipped to deal with adverse MDMA reactions and was not capable of managing airways.

"I think they were struggling to get doctors to work for the festival," Dr Sura told the court.

Counsel assisting the inquiry, Peggy Dwyer, asked if he thought it was unusual for a GP to be asked to provide medical services at a festival of that nature.

"In hindsight, yes," he replied.

In response to his reservations, Dr Sura was told by Mr Hammond there would be intensive care paramedics on site to help.

He said he became "uncomfortable" when he arrived at the site and realised it was approaching 40 degrees Celsius and there was no mobile phone reception.

Dr Sura said his shifts began at 3pm each day and when he finished late about 2.30am, there was no doctor to take over.

He said he did not feel sufficiently equipped to deal with the number of patients presenting at the medical tent.

Lost Paradise founder and director Simon Beckingham told the court he attended meetings with all stakeholders in October and December in the lead-up to the event.

He said the number of doctors and support staff, as well as their qualifications, was left up to EMS.

Mr Beckingham said nobody at the December meeting raised concerns about the medical staffing.

"Was there a discussion that EMS would have to be equipped with adverse drug reactions?" Ms Dwyer asked.

"Yes," Mr Beckingham replied.

"Did you have an expectation that if a patron at Lost Paradise came in suffering from a medical emergency because of the ingestion of drugs, that they could receive critical emergency care?" Ms Dwyer said.

"Yes," Mr Beckingham replied.

The witness said he was surprised to learn Dr Sura was not equipped to deal with adverse MDMA reactions.

Outside court, Joshua Tam's mother Julie said Dr Sura's honesty was refreshing.

"He never claimed to be anything more than he was and he understood that he wasn't qualified to deal with people in a critical emergency situation," she said.

"I thought that was very brave of him."
