Kennard is a familiar face on TV screens after playing the scheming ex-wife of Nothing Trivial lead character Mac and for her roles on Underbelly, Spartacus and Street Legal.
Now she has starred in a short film for national domestic abuse charity Shine. The film was shown at the organisation's 25th birthday celebration last night, at which June Steenkamp, the mother of Reeva Steenkamp - killed by partner Oscar Pistorius - spoke.
Kennard's story of abuse began three months into her first serious relationship. Her former partner was - is - a "beautiful man" with a big heart and a sharp intellect, she said.
But he also had an anger problem triggered by jealousy. "At first I thought, 'That's sweet, it shows he cares'. I'd never witnessed any kind of abuse in my childhood. It was so unfamiliar to me that it didn't make any sense.
"The jealousies turned into anger, and the anger got put on to me, saying things like slut, whore and finding my weak spots, commenting about my weight."
Trying to talk about it didn't work. "You can't speak logically when they've flipped into anger."
On the rare occasions the pair had rational conversations he would apologise and accept he had a problem. Then something would trigger his jealousy again.
The bar incident occurred three years into the relationship, by which time Kennard had learned "not to communicate with any men and to pull in any form of open energy to anybody. At the beginning you're confused. Three years in you're like a dog backed against the wall". Her partner's reaction in the bar was standard by then - leaning into her ear so no one else could hear, and her not wanting to make a scene, but wishing someone noticed. "But nobody hears it. It's just for you."
Other times he followed her home, and she was afraid to turn him away. "Then you end up having to sleep in the same bed. He'd be wanting to cuddle. And you're thinking, 'After everything you've just put me through, now you expect me to love you'? But out of fear you just want everything to be all right, so you cuddle."
A girlfriend was the catalyst for the relationship's end when she stood up to the man.
It's more than 20 years since the relationship ended and British-born Kennard said some hurtful words still triggered old feelings. She also felt guilty when talking to men "in case it's taken the wrong way".
But life had also given her experiences that created the "bag of tools" that allowed her to be "independent, free and who I am".
She wanted others to know they, too, had choices. "If anybody relates to something in my story ... if I knew that somebody picked up the phone to the [Shine] helpline, even just one person, then all of this is worth it."
