Jail school principal's Facebook attack on her students

The principal of the school inside Darwin's notorious juvenile detention centre went on Facebook to attack compensation payouts to four teenage detainees who had been tear-gassed during riots in the Darwin facility.

Lisa Coon who is on leave from the Tivendale School said they were her private views and had nothing to with her post as principal.

She told the Royal Commission into the Protection and Detention of Children in the Northern Territory she had been outraged by the payouts that had ranged between $12,000 and $17,000.

"This was money being paid to boys who had caused thousands of dollars damage," she said.

Ms Coon's Facebook attacks on detainees was drawn to the attention of the royal commission by Phillip Boulten??? SC, counsel for the North Australian Aboriginal Justice Agency.

She was confirming she had banned NAAJA representatives from coming to her school "until they became more professional" when Mr Boulten raised her frequent recourse to Facebook to attack detainees and make adverse comments about news stories in which young people allegedly committing offences would get off scot free.

Her comments came as the four teenagers tear-gassed at Don Dale Youth Detention Centre in 2014 lodged an appeal seeking bigger payouts than awarded last year.

Meanwhile the new Labor NT government announced on Friday that a review of security arrangements at the centre had recommended improved security cameras and electronic surveillance, better training and a full security audit.

The Minister for Territory Families, Dale Wakefield, said the spate of escapes at Don Dale in recent months - eight - was unacceptable and highlighted the urgent need to address security problems.

"Every Territorian has the right to feel safe and expects their homes and businesses to be secure, especially from young offenders being held in detention," she said on Friday.

Conditions inside Don Dale and the treatment of youths in the centre sparked the ongoing royal commission.

Earlier on Friday, a former youth justice officer rejected suggestions he was "indifferent to his basic human needs" when he had not allowed detainee Dylan Voller to go to the toilet during a 500-kilometre vehicle trip between Alice Springs and Tennant Creek that resulted in his prisoner defecating in his shirt.

Bruce Evans and another officer transported Mr Voller, then 17, in handcuffs and he stayed in the back of a van throughout the journey.

He said this was because Mr Voller had been "extremely abusive and threatening" and that the decision to deny Mr Voller a basic human right "was not made lightly".

He said Mr Voller was permitted to urinate out the back of the cage doors "in a secluded spot" on the Stuart Highway.

"You say that if Mr Voller did request to use the bathroom again, you did not believe this request to be serious. Do you recognise the absurdity in that remark?" said Peter Callaghan, senior counsel assisting the commission.

Mr Evans: "Well, yes; however, Mr Voller, due to his threats and swearing and carrying on, may have been trying to get himself out of the back of the vehicle.

"He was continually swearing and being disruptive throughout the journey, would often make false complaints in order to get attention."
