An Australian archbishop who was convicted of covering up child sexual abuse has been sentenced to 12 months' imprisonment, however he could avoid jail after a court ordered that he be assessed for home detention.

Adelaide Archbishop Philip Wilson was found guilty in May of covering-up abuse by notorious paedophile priest Jim Fletcher in New South Wales during the 1970s.

The 67-year-old is the most senior Catholic cleric in the world to be convicted of concealing child sex abuse.

He denied the charges and his legal team made four attempts to have the case thrown out, arguing Wilson suffered from Alzheimer's and so should avoid trial, even though the diagnosis did not prevent him retaining his position in the church.

The archbishop has not resigned, despite standing aside from his duties in the wake of his conviction last month.

He was ordered to be assessed by prison authorities for home detention, instead of jail, and will face court again next month for a decision on where he will serve the sentence.

Wilson will be eligible for parole after six months, court documents show.

In sentencing, Newcastle Local Court magistrate Robert Stone said: "There is no remorse or contrition showed by the offender.

"I am of the opinion the sentence should not be suspended. It does not support the terms of general deterrence.

"On that basis, the only available remaining option is full-time imprisonment or home detention."

The judge justified the home detention option due to Wilson's age, prior good record and that he was unlikely to re-offend.

There was no dispute during the trial that Fletcher, who is now dead, sexually abused an altar boy, with the hearing focused on whether Wilson, then a junior priest, was told about it.

Wilson served as a priest in New South Wales before Pope John Paul II appointed him Bishop of Wollongong in 1996. Five years later, he became the Archbishop of Adelaide.

Abuse survivors have called for Pope Francis to sack of Wilson as archbishop if he does not resign.

The Australian Catholic Bishops Conference, a national body used by bishops to address issues of national significance, said it hoped the sentencing could "bring some sense of peace" to those abused by Fletcher.

"It takes great courage for survivors to come forward to tell their stories," it added in a statement.

"Survivors have been vital in helping us learn the lesson of our shameful history of abuse and concealment.

"The church has made substantial changes to ensure that abuse and cover-up are not part of Catholic life and that children are safe in our communities."

Like elsewhere in the world, Australia has been plagued by accusations that the Catholic Church ignored and covered up child abuse.

A national inquiry into the issue was ordered in 2012 after a decade of pressure to investigate widespread allegations of institutional paedophilia.

The royal commission, which ran for five years, spoke to thousands of victims and heard claims of abuse involving churches, orphanages, sporting clubs, youth groups and schools.

Last month, Prime Minister Malcolm Turnbull agreed to deliver a formal apology to victims of institutional child sex abuse - one of the inquiry's key recommendations.

Another recommendation was that a redress scheme be set up to support victims with counselling, psychological care and financial payments.

All of Australia's state governments have now signed up to the programme, which came into effect on Sunday and offers victims up to Aus$150,000 (€94,000) in compensation.
