Tully, who is serving 14½ years for crimes against eight young girls, has filed appeal papers with the ACT Court of Appeal.

In June, an ACT Supreme Court jury found Tully guilty on 18 counts of rape and acts of indecency against the children.

Justice John Burns sentenced Tully to 14½ years' jail, with a non-parole period of nine years.

But Tully, who is representing himself, has appealed against all 18 charges.

Court documents, filed late last month, cited judicial and factual error as the basis for the appeal.

The offender is expected to argue that Justice Burns caused a miscarriage of justice when he allowed the prosecution to conduct a joint trial of all 23 counts on the indictment.

The documents also said Tully would argue that Justice Burns "erred in allowing prosecutors to lead evidence of the eight complainants as tendency evidence".

The third ground of appeal argued evidence led at trial in relation to five counts had not established that the victim had been under 10 when molested.

Tully will seek to have the convictions quashed and verdicts of acquittal entered in respect to the five counts. The documents said Tully would not seek to put fresh evidence before the court.

It is unknown whether the Crown will launch a counter-appeal.

Tully, 40, has always maintained he did not molest the eight young girls in the 1990s and early 2000s. He claims the victims manufactured the allegations to tarnish his and his family's reputations.

Much of the abuse took place on the Tully family "Hillview" farm in West Belconnen while their parents met for church and community groups.
But some of the assaults also took place in the homes of some of the children.

During the trial, the court was told Tully would supervise the children as their parents gathered for church group, ladies' meetings, and home birthing groups. But he instead used his position of authority to abuse the girls in the shearing shed, laundry, library and bedrooms in the farm's main rammed-earth building. His youngest victim was aged about three or four.

A kitten was used as bait on one occasion, two other children were indecently touched during a piggyback ride, and another girl molested during a game of hide and seek in her own home.

In sentencing, Justice Burns said Tully held an "arrogant belief" the children would not report him or would not be believed if they did.
"You chose your victims because of they were young and vulnerable," Justice Burns said in October.

Tully will be eligible for release in June 2023, unless his appeal is successful.

The appeal has been listed for directions next month and will not be heard until next year.
