Tony Grosser, the gunman who fired thousands of rounds at police during the 1994 Barossa Siege, had his electronic GPS tracking bracelets removed this month.
Grosser was released from jail in 2016 after he served his full sentence of 22-years in prison for one count of attempted murder and five counts of endangering life.
On Grosser's release the Attorney-General applied for an Extended Supervision Order under the High Risk Offenders Act - the first time the legislation had been used on a violent offender - because of concerns he continued to pose a risk to public safety.
Two years ago, on June 15, 2017, Supreme Court Justice Tim Stanley granted extended supervision for another four years, which included two more years of electronic monitoring.
As of June 13 2019, Tony Grosser no longer was required to wear the electronic monitoring equipment.
Grosser suffered from a 'paranoid delusional disorder and believes conspiracy theories concerning police and official corruption'. The court heard that his illness was a substantial contributing factor to his serious violent offending against police.
"While I accept that electronic monitoring is not therapeutic, it serves both a deterrent and protective purpose," Justice Stanley wrote.
"I also accept that the requirement to wear an electronic monitoring device might serve to deter the respondent from engaging in activity which threatens the safety of the community."
Grosser has been electronically tracked since 2016; required to wear a permanent GPS tracker and reside at an approved address.
The conditions imposed by the Supreme Court with respect to Mr Grosser and beyond the standard conditions, relate to no contact, particular with respect to the victims of his offence.
There are also restrictions related to internet access and use, and the use of internet capable devices. There are also conditions imposed requiring Mr Grosser to engage with professional medical services and undertake assessments as required.
According to the act, if Grosser breaches a condition of the orders, he will be sent back to prison.
With the period of electronic tracking now ended, Mr Grosser's supervisions are set by the Supreme Court of South Australia, and are subject to removal or variation through the Supreme Court of South Australia only.
During the 40-hour siege on Moppa Road, Nuriootpa, back in 1994 Star Division police officer Derrick McManus was shot fourteen times by Grosser and was stranded for hours before he could be reached by other officers. He was eventually rescued, survived the injuries, and is now a motivational speaker.
