It can now be revealed that the former student teacher found guilty of sexual offences against a 15-year-old Canberra boy is 28-year-old Petra Shasha, who met the boy during a teaching placement at Canberra's St Edmund's College.

Suppressions on Shasha's name and the name of the school were lifted today in the ACT Supreme Court.

Shasha was found guilty of four out of six charges by a jury last week.

The charges included persistent child sex abuse, grooming and committing an act of indecency, and related to offences committed more than two years ago.

Shasha denied she ever had sex with the boy.

The court heard she first saw the victim when he and his friends pressed their faces against a window to look into a classroom where she was teaching.

The boy told the court she would hang around his group at break times.

Shasha said after she left the school she had 25 friend requests on Instagram from boys who attended the school.

She told the court she ignored them all, but eventually came into contact with the victim, who she said was more persistent than the others.

Shasha said the boy went so far as to ring her on Instagram.

The grooming charges included gifts of clothes and money as well as alcohol and vapes which she lavished on the boy, as well as giving him lifts to school and elsewhere.

The woman was also found guilty of sending him pornographic images and videos that included an image of the pair in a change room in a shop, where the woman was clothed in a G-string.

Case turned on whether Shasha knew victim's age

Because there were three offences proved, Shasha was also found guilty of the persistent child sexual abuse charge.

The case turned on whether the jury was satisfied Shasha knew the boy was 15 at the time of the offences.

The boy admitted he lied when he told her he was 16.

The court heard there was an incident shortly before his birthday when Shasha found his school pass in her car, which suggested he was only 15.

The boy said they both laughed it off.

St Edmund's reported the matter to police, who conducted an investigation that included listening devices to monitor the pair's conversations.

When the boy heard Shasha had been arrested he told his parents he didn't know how he would live without her.

Today, Justice John Burns said there was no reason the suppression on Shasha's name or that of St Edmund's shouldn't be lifted.

Shasha was freed on bail after the trial, and will be sentenced in February.
