Over the next two months, Pomana sent the victim approximately 30 Facebook messages that were 'abusive and threatening'. Two of the messages referred to killing the victim's children.
On May 27, Pomana was seen by police riding a motorcycle with no helmet and no lights. A breath test showed him to have 450mcg in his system, the legal limit being 250mcg.
Pomana pleaded guilty to possessing an offensive weapon, threatening to kill or do grievous bodily harm, driving with excess breath alcohol, and breaching court release conditions.
Judge Philip Crayton said Pomana had "a very poor record".
"It's to your credit that you didn't go beyond those messages and you did, once you had cooled off, stop and perhaps think about it, but this is really the last chance you're going to get."
He fined Pomana $400, disqualified him from driving for six months, and sentenced him to 250 hours of community work.
"You've been give a chance, don't blow it."
