Shortly after 10.30am in Sydney, a Toyota HiAce is claimed to have hit police cars outside Eastwood Police Station in the north-west of the city.
One of the cars was badly damaged, according to New South Wales Police, but nobody was injured.
An hour later, police stopped the HiAce on a street in Ryde, roughly four kilometres from the police station.
There were 13 boxes, each with 21 bags holding 1kg of the drug, police said.
The driver, a 26-year-old man, was arrested and taken to Ryde Police Station.
He was charged with large commercial drug supply, negligent driving, and not giving particulars to police.
The man was refused bail to appear at Burwood Local Court.
Detectives are appealing for dash cam footage from the area between 10.30am and 11.30am, as well as any CCTV or other vision, or information about the van’s movements throughout the morning.
