He then lit a stack of toilet rolls on fire inside the north Canberra house and placed a painting over the hole he had smashed in the front door to gain entry.

Michael Alexander Hoare, 35, pleaded guilty in May to burglary, theft and two counts of property damage.

He appeared in the ACT Supreme Court for sentence earlier this month, and walked free from custody after being handed a partially suspended jail term.

Chief Justice Helen Murrell's judgment revealed the incident at the Franklin home of Hoare's neighbour took place on October 3 last year.

About 4pm that day, having already broken in, Hoare began posting the social media videos.

"Look at my shit I've got. I've got a f---ing TV. I own the f---ing next door neighbour's house. I've got the keys. There's my new car, baby," he said in one clip.

Hoare took a laptop, television, phone, teddy bear, number plates, toolboxes and other items from the neighbour's house and put them in his own place.

He also grabbed a lamp and another television, which he smashed on the shared driveway.

Before leaving for the final time, he lit the toilet rolls on fire, causing unknown damage, and left the neighbour's front door open despite trying to hide the hole he had made in it.

When police knocked on his door that same evening, he went to the back of his property and yelled at them not to come in or he would "blow this place up".

He threatened to shoot police and burn his house down during the subsequent stand-off before lighting a fire in his backyard, scorching the house and melting part of the clothesline.

Firefighters, who were already on standby, extinguished this blaze and Hoare was eventually arrested.

During court proceedings, Hoare's neighbour provided a victim impact statement saying he felt unsafe living next door after what he perceived as "a campaign of intimidation".

In sentencing, Chief Justice Murrell noted most of the stolen items had been recovered.

But she said Hoare's offending involved "irrational conduct" targeted not at a stranger but a neighbour, who had arrived home to find "gratuitous ransacking".

This had included air conditioning and heating panels being ripped off the walls.

"The damaged television and lamp remained on the shared driveway to greet the complainant when he returned from holiday - a very unpleasant introduction to what had occurred," the judge said.

Chief Justice Murrell said Hoare had several previous convictions, mostly for drug-related matters.

She accepted that he was suffering from "an episode of acute psychotic illness" at the time of this offending, though it was unclear whether it had been drug-induced.

Chief Justice Murrell ultimately sentenced Hoare to 12 months in jail, suspended after the 102 days he had already spent in custody on remand.

She placed Hoare on good behaviour orders for nine months, directing him to comply with psychiatric treatment orders and to accept the supervision of Community Corrections.
