The teen heart-throb was on the roadside set for just an hour for a fight scene where it appeared he came off second best.
In their efforts to block The Advertiser 's exclusive shots, the film crew and minders closed the road and claimed "ownership" of the town of about six buildings, east of Port Augusta.
"We own this town," a film producer told The Advertiser.
Minders used umbrellas and trucks to keep intrusive cameras off the star, who appeared to be sporting a close-shaved haircut for the role.
He also looks to have forgone his clean-cut look for the movie and has a three-day growth.
The scene featured Pattinson staggering out of the passenger side of a ute before being beaten to the ground by the driver.
Extras and a potential stand-in for Pattinson were also in Hammond for the filming and had earlier been in nearby Quorn where Pattinson is said to have had a drink at one of its pubs over the weekend.
Earlier yesterday, The Rover crew was filming at an even more remote location, the largely deserted town of Bruce.
The Rover is understood to be shooting at locations deeper in to the Flinders Ranges for the rest of this week and next month as far north as Marree.
The stars of the film and some of the extras are understood to be staying in Port Augusta while the movie's production centre has been set up in the Quorn Town Hall.
On set, the stars are well catered for as temperatures reach the high-30s this week - they have two airconditioned motorhomes.
Pattinson flew into Adelaide on January 18 - minus actress girlfriend Kristen Stewart - and spent more than a week around town, meeting the film's producers at the SA Film Corporation's new Glenside studios
The Twilight star was spotted having dinner on Gouger St with The Rover director David Michod and producer Liz Watts.
Pattinson was also photographed riding a bike around the Rivers Torrens without a helmet - an offence that earned him a warning from the police.
