The strip searching of minors in Tasmania is systemic and something must be done to ensure the practice is in line with "basic human rights", the state's children's commissioner says.

New figures from Communities Tasmania show there were 203 strip searches of children at Ashley Youth Detention Centre in a three-month period last year.

Of that number, 113 were conducted on Aboriginal or Torres Strait Islander young people.

None of the searches resulted in the discovery of contraband.

Recent cases involving the strip searches of minors have brought attention to the practice.

Last month, an 11-year-old boy was subjected to a mock arrest involving him being strip searched by an off-duty police officer and held in custody, in a bid to curb his behaviour.

The case has been referred to the Integrity Commission.

It followed the story of a 13-year-old Aboriginal girl who was strip searched while being held in custody overnight.

'Not acceptable', advocate says

Leanne McLean, who took over the role of children's commissioner last year, has received a briefing from the Justice Department about the practice.

She said she could not comment on the individual cases, but said it had drawn attention to the broader practice of law enforcement strip searching of minors in custody.

"I am concerned at a systemic level, about the strip search or full search as a routine practice," she said.

Ms McLean said she would write to the State Government in the coming weeks to provide advice on the issue.

"That will basically outline a better approach to how we might consider children and young people who find themselves in this situation that is more in line with basic principles of human rights," she said.

Ms McLean said every child and young person had the right to feel safe.

"The routine strip search of young people is not acceptable, we should have a proportionate risk-based approach," she said.

In a statement, Human Services Minister Roger Jaensch said there was already a review of procedures to ensure the safety obligations of staff and inmates were met and he would welcome input from the commissioner.
