Police located five males at an address on Scenic Dr, along with the till, cigarettes and other property taken from the dairy.
The arrest happened within an hour of the robbery.
"A speedy response from police to the scene and a rapid investigation by the Tactical Crime Unit has resulted in the arrest of five people and the seizure of a vehicle," Miller said. "This was a solid piece of police work, which included a foot chase by officers."
The shop assistant was injured but did not require treatment, Miller said.
Five males, one aged 18, three aged 17 and one 14-year-old, appeared in court this afternoon, where police opposed bail.
"Police will not tolerate this type of crime, which targets people providing a vital service to our communities," Miller said.
