The father and son, who cannot be identified because the boy is a juvenile, also recruited one of the 14-year-old's mates to assist in an armed robbery and a break-in before committing another robbery and attempting another two break-ins between May 22 and June 16, according to court documents.

The boy pleaded guilty to three counts of armed robbery, two counts of aggravated break and enter and robbery in company, while other attempted break-ins and robberies were taken into account when he was jailed for a maximum of three years in Broadmeadow Children's Court on Friday.

The longest jail term in the children's court is two years for one offence, but magistrates can impose an aggregate sentence of three years for multiple offences.

Magistrate Andrew Eckhold found the boy's crime spree fell into that worst category, but ordered the boy serve a 10-month non-parole period due to his mental health and drug dependency issues, making him eligible for parole on May 27.

The boy's father pleaded guilty to five offences in Newcastle Local Court in March and will be sentenced in June.

The crime spree started in the early hours of May 22 last year when the man, his son and his son's mate smashed their way into a shopping centre at Elermore Vale.

The trio - who had black face coverings and gloves on - then ran directly to the IGA Liquor store and forced their way in by dislodging a locked roller door.

The three then started going through the cash registers and chucking bottles of alcohol into a shopping basket. They couldn't find any cash but stole nine bottles of spirits. Less than half-an-hour later, the trio arrived at a Sandgate service station. The father waited outside the store to keep watch while his son and the other boy - who were armed with a sword and a baseball bat - ran inside and threatened the employee behind the counter.

They smashed things and jumped the counter, stealing $1200. Four nights later, the father and son held-up another service station at Williamtown. This time the father went inside and stood guard over a terrified staff member, repeatedly hitting him in the shoulder with a bat and saying: "Give me the money. Give me the money".

As this was happening, a customer walked into the service station and saw the employee cowering behind the counter. The father saw the customer and began chasing him around with the bat, yelling "I'm going to f---ing shoot you." The father and son fled with more than $1000. The father and son later tried to break into the BWS at Medowie on June 10 and 16, but were unsuccessful.

Before their arrest, the boy was heard on the phone speaking in pig Latin to his father saying they needed to get rid of anything linking them to the robberies.

"Kinda need to etgay [get] idray [rid] ofray [of] everingshay [everything]," he said.
