CATHY McGowan campaigners will explore new security measures, after their Wodonga headquarters was targeted twice in six days.
A window in the front door of the Beechworth Road building was found smashed on Monday morning, less than a week after a glass panel beside it was also shattered.
Police say two paving blocks from the front garden at property were used to cause the damage.
A rock was also found inside following the incident, which The Border Mail understands occurred sometime between Friday afternoon and Monday morning.
Wodonga police were investigating the determine whether the damage caused on both occasions were linked.
Campaign co-ordinator Denis Ginnivan said he would leave it to officers to determine who was responsible.
“Basically someone's thrown a brick through the window… there was glass all over the floor,” he said.
“We don't know who did it and nothing has been taken.
“We do need to be careful about it happening again, we will take advice from the police on what to do.
“We will look at security options.”
Police said it was too early to tell whether the attack was politically motivated.
Independent Member for Indi Cathy McGowan said the matter was being taken seriously.
“We don’t know who is behind it, and it’s disappointing this has occurred,” she said.
Wodonga Detective Senior Constable Andrew Leonard said he expected there would have been heavy foot traffic in the area given the long weekend and revellers returning from the Rutherglen Winery Walkabout.
He said the police were keen to talk to anyone with information on either incident.
“Obviously its property that belongs to someone else, I can’t see the point behind in vandalism or property damage,” he said.
“At this stage we don’t believe there was injury or anything stolen… it's not being investigated as a burglary.”
Anyone with information should contact Wodonga police on (02) 6049 2600 or Crime Stoppers on 1800 333 000.
