On October 9, Morrison drove a vehicle, which had been unlawfully taken, to the ANZ bank in Greerton, which he entered partially disguised, carrying a note that said "this is a hold-up". He passed the note to the woman at the counter, carrying a bag with a stick inside, which was made to look like a gun, and demanded money.
He fled with more than $5500.
Judge Cooper said Morrison's offending had greatly impacted on his victims. "The [victim] had to take time off work because of the stress she was under ... The same occurred with the [other victim] who is still fearful and anxious about what you did ..."
Judge Cooper said he could not decide which was the greater charge, as in the ANZ incident, no real weapon was used, but there was a greater degree of pre-meditation and more money was taken.
Morrison's lawyer, Andy Schulze, said a hurdle in a personal relationship had partially caused Morrison's offending to "spiral out of control".
Mr Schulze said Morrison accepted what he had done was wrong.
In reaching the sentence, Judge Cooper took into account Morrison's previous convictions, including multiple dishonesty charges, and his early guilty pleas.
