Lawyer George Linder said the strong prospect of jail had awoken Newcombe. The "penny had dropped" and he realised he did not choose his friends well and was easily led.
"He knows these were stupid, silly actions. He's very remorseful and loves animals, this is not his usual behaviour."
Mr Linder opposed the request for an order for emotional harm for the owners of the goat, saying Newcombe could not afford it, but that submission angered the judge.
"He's got enough money to drink. So all the money he's not putting to drink can go to the reparation," Judge Neave said.
"You told police that you were being a dickhead. It's hard to disagree with that description," the judge said to Newcombe.
"You have come very close to a sentence of imprisonment here."
Newcombe was instead sentenced to four months' community detention, 150 hours' community work, 12 months' supervision and $500 reparation for the owners of the goat at $50 a week.
