Human Rights Commissioner Helen Watchirs told a hearing on Wednesday her office did not have sufficient staff to conduct an audit of Canberra's jail.

Dr Watchirs said her office would "absolutely" want to review conditions at the jail, including overcrowding, if it had the resources to do so.

"There's not sufficient resources to do a review of the male prison and the overcrowding, it's just the female area which is between 12 and 15 detainees," she said.

Dr Watchirs said a full audit would cost between $200,000 and $300,000 and would take one to two years with two staff members.

Earlier in the hearing, the Human Rights Commissioner said a review would begin soon to look at resourcing issues in the ACT's human rights agencies.

Last month Attorney-General Simon Corbell said the government would consider a restructure of the agencies to address concerns about under-staffing.

Mr Corbell said that could include the sharing of back-of-house services to free up funds for frontline staff.

It followed complaints from the territory's public advocate Anita Phillips in her annual report that the caseload for her office was far too high for staff members to cope with.

Ms Phillips wrote in her report that some mental health patients in the territory's health and prison systems had gone without advocacy as a result.

Dr Watchirs told Tuesday's hearing that an amalgamation of the offices of the Public Advocate, Victims of Crime Commissioner and the Human Rights Commissioner was one consideration of the review, which will conclude next year.

"Anything that would result in more services because of efficiencies, I think would be what we would want," she said.

"So long as it doesn't mean that our present resources are diluted."
