Young's plans involved a slew of violent acts, detailed in court documents.
"He stated he would smash his ex-partner's car windows, drag her out of the car, pull her hair and smash her teeth through her skull," a police summary said.
"He also said he would put a chain around her neck, tie her to his ute and drag her along until she is dead."
Young told the staff members he was passionate about hating his former girlfriend and wanted her dead - "this is one of his biggest wishes", the summary said.
The defendant was assessed under the Criminal Procedure (Mentally Impaired Persons) Act and found fit to stand trial, which brought about a guilty plea to the charge of threatening to kill.
Defence counsel John Westgate said his client was now receiving psychiatric help and was "much better".
Young had strong support from his parents, was in a new relationship and had a job, he said.
Judge Phillips noted the man had no previous convictions.
He sentenced Young to 100 hours' community work and nine months' intensive supervision.
A protection order was granted in favour of the victim.
