The mother of international tennis star Nick Kyrgios remains consumed by "trauma and fear" after a man pointed a gun at her and stole her son's Tesla, the ACT Supreme Court has heard.

A 33-year-old Canberra man pleaded guilty earlier this year to aggravated robbery over the theft in May last year.

A victim impact statement from Norlaila Kyrgios was read out in the ACT Supreme Court by her daughter and Mr Kyrgios's sister, Halimah Kyrgios.

She said she was "shocked to the core" when she was "confronted by a masked figure with cold eyes", who the court heard was brandishing a firearm in her direction.

"What was stolen from me that day was far more than a vehicle. It was my sense of safety, my peace, my ability to feel safe in my own home," her statement read.

"But more devastatingly, my belief I could protect my family."

Ms Kyrgios was so distraught following the ordeal, she sought refuge with family in Malaysia, but said she continued to feel "overwhelming distress".

She said she had sought professional help but said no therapy could erase how she felt and despite installing extra security, she no longer felt safe in her own home.

A statement from Mr Kyrgios was also read to the court, in which he described himself as "incredibly angry".

"Nothing prepares you to be woken up by your mother's screams," he said in the statement.

"I have been unable to sleep … constantly worried about the safety of my family."

Offender apologetic for actions

The offender, who has been in custody since the incident, also read a statement to the court, in which he acknowledged the "seriousness" of his actions and apologised.

"I now understand how my actions … fill you with trauma and fear," he said.

He said he had battled with addiction and had been involved in criminal conduct from a young age, but said he had "never steered away from the opportunity for change".

He said he had a detailed relapse prevention plan and did not want to spend the rest of his life in institutions.

"Right thoughts turn into right behaviours," he said.

"I have already missed out on so many important years of my life."

Both the prosecution and defence agreed a term of imprisonment was warranted.

Prosecutor Marcus Dyason said there was a level of premeditation, arguing the man's conduct was at the "upper end of the range", noting the "long-standing ramifications for this family".

He also highlighted the Tesla's value was $125,000.

Defence lawyer Dr Jan de Bruin said his client was someone who wanted help and was "clearly looking at what support he [could] get".

He said he had "good prospects of rehabilitation".

The man responsible for the theft is the same man who hit and killed 21-year-old Canberra woman Clea Rose in 2005.

He was remanded in custody and will be sentenced in July.
