Convicted murderer Michael Vernon Lowe, 52, has pleaded guilty to breaching a family violence order earlier this year.
Lowe, previously of Waverley, contacted his former partner from prison while he awaited trial for the murder of Darren Booth in 2012.
Lawyer Adrian Hall said Lowe would call the woman's parents, who he used to live with, and she would occasionally speak to him over the phone.
This contravened the order that was made in June 2012, a month after he stabbed the woman's then boyfriend to death in her Kings Meadows home.
The Outlaw motorcycle club member was sentenced on Monday to 20 years jail for Mr Booth's murder.
Speaking via video-link from Risdon Prison, Lowe told the Launceston Magistrates Court that he opposed any extension of the family violence order.
Magistrate Reg Marron recorded a conviction and dismissed the application to extend the order, which was not opposed by the prosecution.
