The Seven Sharp presenter exposed the comments by posting screenshots of them on social media this afternoon.
"There are lots of lovely men in the world and then there are these guys having a discussion about me on my Facebook page. #everydaysexism #dicks", she posted on Twitter.
Barry redacted the names of the men in the screenshots.
One said "such a milf", to which another replied "yeh bro very do-able".
Another person said "she'd talk all the way through it", to which one replied "put something in her mouth to keep her quiet".
In response to the men, Barry said: "I suspect whatever you planned to put in my mouth would be so tiny it would do little to keep me quiet."She pointed out their comments were visible to herself, as well as her mum and sons.
"Need I go on? Maybe your New Year's resolution could be how to treat women with a bit more respect? Regards, Hilary."
Earlier this year Barry was told to "dress properly" by a man on social media.
He was referring to an off-shoulder top Barry wore while hosting Seven Sharp with Jeremy Wells.
"Please encourage Hilary to dress properly. Exposed shoulders are for the young," the man wrote in a Facebook post to the show.
Barry called out the man's age shaming.
"Just for the record, I'll wear what I like, when I like."
She then posted a photo of her basking in the sun on a beach in togs, with a message of empowerment to other women.
"This is for every Geoff who ever told a woman what to wear or what part of her body to cover up. We will not be told. Not now. Not ever."
Last year a Seven Sharp viewer who was upset over what she deemed was too much of Barry's cleavage on TV was moved to make a complaint to the show.
In her email Barbara accused Barry's fashion choices of being unprofessional and expressed dismay that such a display could happen in the #MeToo era.
"We are being assailed by more and more of Hilary in low-cut tops exposing her cleavage. Unfortunately it's become a worldwide trend which is mind boggling considering we have the #MeToo movement trying to stop women being treated as sex objects," she wrote.
But Barry wasn't having a bar of it.
"Well here's the thing Barbara, I'm just a middle-aged mother of two who slapped on some lippy and a pretty top to look presentable for the nation," she said before adding, "I'm sorry that you find my boobs offensive."
On Thursday, she posted a picture of her wearing a colourful frock with the caption: "Final #newscleave of 2020."
