"Without the bull bar the divi van would be a write-off," Port Fairy police Sergeant Dave Walkley said.

"There's damage to the bull bar, front panel and under the headlights.

"When I was rammed the front of the divi van was lifted completely off the ground. It was a very deliberate action."

Sergeant Walkley said the wanted Colac man in his 20s had been involved in a crime spree stretching from Geelong to Port Fairy.

"A lot of serious offending will come out. Fortunately the impact of the ramming disabled the white Commodore sedan and he's had to dump it.

"When he first tried to ram me at the service station I noticed he had a flat tyre.

"He was obviously looking for a place to change the tyre."

The Port Fairy police station commander said he had pulled up sore after the incidents on Wednesday morning.

"The ramming was clearly intentional and it wasn't the first time in the past couple of days he's tried to ram a police vehicle," he said.

"I had to pull forward a metre taking evasive action at the service station to let him get behind me because he clearly wasn't going to stop," he said.

"The white Holden Commodore sedan had distinctive black rims and every time we saw it the vehicle had a different set of number plates.

"There were also four people in it and it was also noticeable because it was low in the rear," he said.

A 20-year-old Colac man appeared in Warrnambool Magistrates Court on Thursday charged with more than 50 offences including conduct endangering life, negligent driving and other traffic related offences.

The man appeared briefly for a filing hearing.

He did not apply for bail and was remanded in custody until May 15.

The court heard there were four police briefs, with the most recent containing 32 charges.

Lawyer Xavier Farrelly said the man was possibly withdrawing from ice and had an acquired brain injury following a motor vehicle accident in 2012.

Anyone witnesses or anyone with dash camera footage of the incident is requested to contact the Warrnambool police station or Crime Stoppers on 1800 333 000.

Earlier: A Colac man in his 20s who rammed a Port Fairy police divisional van and was clocked in Geelong at more than 200km/h will appear in Warrnambool court on Thursday.

Detective Sergeant Andrew Raven, of the Warrnambool police crime investigation unit, said the man had been charged with about 30 offences, including ramming a police vehicle, attempting to ram a divi van, dangerous driving while pursued by police, possessing ice and reckless conduct while driving.

A preliminary drug oral fluid test was positive to methamphetamine and has been sent off for further analysis.

Police said a white Holden Commodore sedan had been involved in a number of evades of police and police pursuits since last Sunday in the Geelong, Colac and Winchelsea areas.

The driver was allegedly clocked by a Geelong police highway patrol member at 204km/h in one incident.

"The officer was stationary on the side of the road and just saw a flash go past," Detective Sergeant Raven said.

Wednesday's drama started mid morning when a Port Fairy police officer saw the white Holden sedan on Woodbine Road near the Port Fairy Golf Course.

"The sedan was clocked on radar at 146km/h going towards Port Fairy," Detective Sergeant Raven said.

"It's next seen at a service station backed into a car park with four people onboard.

"The divisional van driver pulls in front of the white sedan, partially blocking it and the offending driver revved his vehicle and tried to move off.

"The divi van driver has then had to take evasive action to avoid being involved in a collision."

Detective Sergeant Raven said the offender went over gardens beds to escape and headed west on the Princes Highway towards Yambuk.

"The Commodore sedan is next seen by police officers heading back into Port Fairy and turned into a private driveway," he said.

"When the divisional van tried to block the white sedan and offender has tried to force his way out and collided with the front of the divi van.

"Both vehicles received significant front-end damage."

Damage to the police vehicle has been estimated at just under $10,000.

"The white sedan driver was able to evade being blocked in and then headed east on the Princes Highway," Detective Sergeant Raven said.

"He's then seen in the Mortlake Road area of Warrnambool and about 11am dumped the Commodore sedan in the AquaZone car park. The four people onboard fled on foot," he said.

"The male driver was arrested soon after nearby and a Colac woman in her 20s was also taken into custody.

"Colac police detectives expect to speak to another Colac man in coming days and follow-up inquiries will also be made with a Warrnambool woman in her mid 20s who has previously had involvement with the courts."

The investigator said that two other men were arrested for unrelated matters, processed and released.

"One bloke was just walking along the street, but he was wanted on a warrant and arrested," Detective Sergeant Raven said.

"The initial description of the second man we wanted to speak with was a man wearing a beanie with a neck tattoo.

"A Corangamite police officer arrested that unrelated man. Another man wanted in relation to a car theft committed in February was also arrested, interviewed, charged and bailed to appear in court.

"It was pretty hectic for a while."

The driver of the Commodore is known to police in the Corangamite/Colac region and has family connections to the Warrnambool district.

He will appear in the Warrnambool Magistrates Court for a bail/remand hearing on Thursday.
