"I'll get your car and f... burn you in it," one said.
Later, Cavanagh added, "f... you watch your f... back I'm coming for you."
de Jager said the defendant had battled substance addiction and was also receiving treatment for a "diagnosed condition".
A recent test proved the man was now drug free, he said.
Judge David Robinson acknowledged that was a positive step but a report compiled by Probation on Cavanagh in February cast him in a less favourable light.
The defendant openly admitted breaching his bail by contacting the victim by cellphone and he showed an unwillingness to do a rehabilitative programme.
He had done a Stopping Violence programme three times and it had not worked, he said.
The report writer said Cavanagh appeared to believe his offending should have no consequences and that any sentences imposed simply stopped him "moving forward" with his life.
