But it was not a case of him rushing into the world before they could get to the hospital.

It was a carefully planned home birth, part of the ACT's publicly funded trial.

He is one of 35 babies to be born through the trial that has at times been criticised for being too restrictive and, as a result not, producing a large enough sample.

Women had to live within 15 minutes of Canberra Hospital, had at least one baby but not more than four, be considered low risk and agree not to have a water birth.

The trial began in 2016 and the first birth was in January 2017.

While the trial has been deemed a success in an internal review, which evaluated 17 births, not everything has gone to plan.

The review, which examined births up until October 2018, published on Monday was internal and a final external evaluation will be completed in the coming months.

It said three babies had been born before the arrival of the midwife, and one of these women also experienced post-partum bleeding.

She had declined an active third stage of labour - despite this being a requirement of the trial - but agreed to the appropriate medication once bleeding increased.

She was one of two women who had to be taken to hospital by ambulance during the trial.

Another woman had an unplanned water birth at home, also against the eligibility criteria.

While all women delivered at home, some had to be taken to hospital either by ambulance or by private car for additional care.

The trial was strictly for women who lived in the ACT but, according to the report, one NSW woman moved temporarily for two weeks to get around the residency requirements.

The report noted areas of improvement relating to proper documentation, processes, data integrity, risk management and reporting.

The review made 14 recommendations including that an ambulance is called for a birth that is occurring before a midwife has arrived.

While identifying areas that needed improvement, the report said the trial was a success story, with all babies healthy and delivered through vaginal births at home.

"This is a remarkable achievement and clearly demonstrates that the safety, quality of the services, skill and expertise of the midwives and the governance processes are working," it read.

Ms August said the trial should be extended so women who lived beyond a 15 minute drive from Canberra Hospital could take part.

"It was liberating and a huge relief," she said of her experience. "I had complete confidence. I felt far more comfortable staying home.

"The mess is remarkably small."

Canberra Hospital's executive director of women, youth and children Tina Bracher conceded there were things to improve.

A final review won't be completed until 40 births have occurred, which is deemed an appropriate sample size.
