A child sex offender who was jailed indefinitely in 2010 because of an "unacceptable risk" he would commit a "serious sexual offence" if set free has been released into the community under a strict eight-year supervision order.

In a judgment handed down by Supreme Court Judge John McKechnie, Alwyn Wayne Brown was deemed to be a "serious danger to the community" but was released to live in Melville under strict conditions, including a daily curfew.

Brown has spent most of the past 14 years in prison for a series of sexual attacks on girls aged six to 12.

Brown will be required to live at a specified address in Melville and undergo libido-suppressing drug treatments and counselling. He was also ordered to have no contact with his victims or any child under the age of 16 years of age.

The judgment noted Brown had made "significant progress" during counselling sessions towards "better understanding his offending behaviour". Brown had also voluntarily taken anti-libidinal medication to "manage his deviant sexual fantasies by diminishing sexual arousal".

Following the introduction of the drug Androcur, Brown reported a decrease in sexual fantasies and blood tests had shown a decrease in the level of testosterone post medication, the judgment said.

Brown's treating psychologist had pointed out that there were benefits for treating within the community as opposed to prison.

"Certain issues cannot be particularly addressed in prison because the person is not exposed to certain circumstances, such as being in a relationship, dealing with regular domestic issues, or self-management in the community," the judgment said.

Judge McKechnie said the supervision order had to be lengthy, but "not so long as to crush all hope by being so burdensome that the respondent loses motivation to comply". He recommended a review of the terms of supervision in two years.

In December 2010 Supreme Court Justice Eric Heenan ruled in favour of the Director of Public Prosecution's application for an indefinite detention order for Brown, and said there was an "unacceptable risk" the 40-year old would commit a "serious sexual offence" if set free.

Brown was due to be released in June 2010, having spent all but six months of the prior 12 years in prison for child sex offences, but his jail term was extended.

Brown was jailed in 1999 for luring a six-year-old girl from a Broome hostel and attempting to sexually penetrate her. He was released in July 2003 but was returned to jail in December that year for sexually abusing a 10-year-old girl in Morley, an offence for which he received a 4½ year jail term.

In 2007, DNA evidence linked him to a November 2003 sex assault of two girls aged eight and 12 years old. Brown took the sisters into a storeroom of a unit under construction in Bedford before blocking the door so they could not leave and committed an indecent act. Two years were added to the prison time he was already serving.

Between 1995 and 1997 he was convicted of a number of sexual assault offences in NSW. In November 1998 he was convicted of three counts of wilful and obscene exposure in public in Victoria.
