A review has been called into security at South Australian parliament after a man allegedly crashed his car into a roller door in an attempt to enter the building.
Police were called to North Terrace about 5.50pm on Tuesday after reports a black Audi sedan had been driven into an external roller door leading to a secure car park.
The Adelaide man is alleged to have approached several employees as he attempted to gain entry to the building.
Speaker of the lower house Dan Cregan said the man was seen re-entering the car park soon after 11pm.
The 42-year-old was detained by security officers until police arrived to arrest and charge him with property damage.
He was released on bail as he awaits an appearance at Adelaide Magistrates Court in January.
Police did not consider the incident an intentional attack on Parliament House, Mr Cregan said.
SA Police Senior Constable Matt Brown told ABC Radio no one was injured and all employees and MPs went home safely.
Premier Peter Malinauskas said he was not concerned about the incident but believed a review was appropriate.
"We're very fortunate in South Australia to have a parliament that is accessible to the public," he said on Wednesday.
"Of course there needs to be a degree of security but I don't want that security to be over the top and at the moment I think it's a balance we've got right."
SA Treasurer Stephen Mullighan was at parliament at the time of the incident but only learned of it when it was reported on Wednesday morning.
Mr Mullighan said security arrangements had been significantly beefed up following a deadly shooting at Canada's Parliament House in 2014, with multiple security checkpoints throughout the building.
"And that obviously has worked to some extent here where that person was not able to access Parliament House proper, despite making it into the underground car park," he told ABC Radio.
