An Adelaide woman acquitted of terror offences had ongoing contact, including a marriage proposal, from the notorious Clavell family while she was behind bars, a court has heard.
Zainab Abdirahman-Khalif, 24, was found guilty of being a member of the Islamic State terror group following a jury trial last year.
But the verdict was set aside and she was acquitted in a Court of Criminal Appeal majority decision last month.
On Wednesday, Commonwealth prosecutors argued that despite the court's decision, her movements should be controlled by a court order.
In reasons outlined in the Federal Court, prosecutor Andrew Berger said Ms Abdirahman-Khalif had gained notoriety after her acquittal and could be contacted by other extremists.
He said an example of that was the letters she exchanged behind bars with the sons of Rodney Clavell, who was found dead after a stand-off with police at an Adelaide brothel in 2014.
Mr Berger said Nathan Clavell wrote to her in August asking whether she would be interested in marrying Daniel Clavell.
"In the letter she was asked twice to contact (a woman) upon her release so that they could talk more, and a telephone number was provided," he said.
Daniel Clavell was in 2014 jailed for three years, four months for driving, drug and assault offences, and, at the time, said he would rehabilitate by turning to Islam.
Earlier this year, two other sons, Joshua and Joel Clavell, were shot by police after they allegedly attacked officers with a tomahawk and knife.
Mr Berger said suggestions Ms Abdirahman-Khalif has renounced her extremist views could be treated as a "self-serving" bid to satisfy parole requirements.
But he said the aim of the control order would be to protect her and the community rather than punish her.
Among the 21 controls sought are to report to police once a week, not leave Australia, live in an approved premises and comply with a 10pm-6am curfew.
Ms Abdirahman-Khalif, a former nursing student, was stopped by police at Adelaide Airport while trying to board a plane to Istanbul in July 2016.
In acquitting her of the terror charge, the appeals court said while commonwealth prosecutors had proven Ms Abdirahman-Khalif was a supporter of IS and planned to travel to Syria to make contact with members, no evidence had been presented about the group's membership processes.
Therefore it was not possible to prove a connection between her actions, communications, pledge of allegiance and travel plans with formal or informal IS membership.
The case will return to the Federal Court later this week.
