​Penny Fran Simon, 47, of Ocean Grove, Warrnambool, pleaded guilty in the Warrnambool Magistrates Court late on Wednesday to being drunk and disorderly, acting prejudicial ​to the good running of a jail, making threats​, possessing cannabis​ and two counts of trespassing ​and three of offensive behaviour.

Police said ​Simon ​was sent a notice banning her from Warrnambool’s Centrelink office in Lava Street from June 28 due to her escalating aggressive and ​abusive behaviour.​

She was given a staff member's number to contact if needed.

The court was told that on July 6 Simon went to the office of South West Coast MP Roma Britnell in Liebig Street.

She was highly intoxicated ​and ​screaming at staff ​which prompted them to lock the doors.

​The next day ​Simon went back to Centrelink in breach of her barring order where she was aggressive ​and abusive​.

​Simon told a staff member "wait until ​you're ​out in the street …  you're gone"​.​

On Tuesday at 1.30pm police were again called to Centrelink because Simon was drunk​.

She was highly abusive to police officers and after being arrested, threw the contents of her pockets at officers at the police station.

In a search of her possessions, police found 1.5 grams of cannabis.
