A senior Bendigo Catholic leader is "deeply disappointed" in the person who removed from a "loud fence" at the city's cathedral.
The ribbons are both a protest and an acknowledgement of the church's role in institutional sexual and other abuse and have appeared regularly on fences of religious institutions.
The Very Reverend Brian Boyle said he found out someone had them down late on Wednesday afternoon.
Dr Boyle did not know who took the ribbons down when he spoke to the Bendigo Advertiser on Thursday.
"I would welcome individuals or groups to put ribbons back on the fence surrounding the Sacred Heart Cathedral in Bendigo to show support for those who have suffered from sexual abuse," he said.
Dr Boyle was planning to add more ribbons either later on Thursday or sometime Friday.
He was also preparing to address the matter in a church bulletin that would likely circulate over the weekend.
"In the bulletin, I will be suggesting that the whole purpose of the ribbons are to draw attention to the silent suffering that so many people have been through over the last several decades as victims of sexual abuse - particularly as it affects the Catholic community in this country," Dr Boyle said.
"The ribbon's presence there [at the cathedral] is a silent witness to those who have been through that sort of suffering. We need to acknowledge that as a primary duty as the Catholic community in this country."
Dr Boyle said it was hard to know why someone would think it would be appropriate to remove the ribbons
He said that he would be distressed if it turned out to have been a member of the Catholic community.
"I would hate to think that anyone would think this was a good or dutiful thing to do," he said.
"It is quite the opposite. It is ignoring the pain of so many people who have suffered."
