A man who allegedly stalked two South Australian members of parliament has been cautioned, police have revealed.

The women have been named as SA Education Minister Lucy Hood and MP Ella Shaw.

The 44-year-old man from Adelaide’s northern suburbs was issued with stalking cautions in relation to the MPs. They relate to separate incidents involving Hood and Shaw and are not connected.

The man was also charged with an unrelated offence of breaching bail.

He was arrested on Tuesday afternoon and will face court on November 27 on the breach of bail charge. He has not been formally charged with stalking.

Hood and Shaw spoke out on Wednesday, with Hood saying their shared overwhelming feeling was “frustration”.

Hood first reported the man about three years ago. He was also cautioned then.

“I felt that the police acted appropriately, and I absolutely felt supported, and I believe that they took the appropriate course of action,” she said when asked if there should have been quicker police action.

Hood declined to provide further details about how many times she had reported the alleged stalker.

“We are women who love our communities, who put our hand up to represent their communities in the state parliament, and really, we would love to be here talking about our communities today,” she said.

“It is a sad occurrence that the political discourse has moved to such a level that we see young women in our parliament who are having to come up with this behaviour.”

Shaw said the behaviour was “unwanted” but would not deter her from doing her job.

“I’ll definitely not stop door-knocking, attending community events. That’s the exact reason that I’ve been elected to do this job … to advocate for my community,” she said.

Hood has spoken out previously about harassment she has received, including being targeted with abusive graffiti on a wall in central Adelaide earlier this year.

Shaw became the youngest person elected to the SA parliament at the March state election.

Last week, she said she no longer posted online in real time, after an incident where she was tracked and followed to her car.

Shaw said she posted an Instagram story about attending a community event only to find a person who had repeatedly messaged her on social media was waiting outside when she left. The New Daily does not suggest that incident is linked to the current caution.

As a backbencher, Shaw has only three staff members in her electorate office and monitors her social media content herself.

New SA Police Commissioner Linda Williams and another officer will brief state MPs on their safety on Thursday.

The developments come amid a surge in public threats and heightened awareness following the alleged attack on Victorian MP Helen Haines, in which she lost both her legs.

The briefing is expected to cover security measures at electorate offices and general parliament safety protocols, including access and how to report abuse or threats.
