Kaz's main storylines have centred on her idolizing of Bea Smith and being a vigilante against men who abuse women.
The SoHo Wentworth website states, "At first just a rowdy onlooker during Bea’s sentencing, Kaz Proctor is a perfect example of a dangerous effect just waiting for a cause.
Damaged by growing up in a dysfunctional household with a violent and sexually abusive father, further scarred by experiences with angry boyfriends, she’s come to believe all her problems are caused by the violence men inflict on women.
Her intensity and hair-trigger temper make her a pretty difficult partner, and she's got a string of failed and acrimonious relationships behind her to prove it.
[5] Offscreen, it is believed that Kaz plants Harry's murder weapon at Will Jackson’s house and tips off the police.
[9] When the conjugal visits are declined, Kaz makes plans and causes a nudity riot in the exercise yard.
[10] Kaz and Allie (Kate Jenkinson) watch as Ferguson (Pamela Rabe) is brought into the general population.
[11] Kaz took center stage in her own flashback episode where it focused on her grieving for her sexually abusive father.
Kaz takes on the position of top dog and tells Bea she won't let the girls down.
The woman laugh at Kaz when she doesn't feel the need to punish the women or Ferguson over the attack in the yard.
A few weeks later, Kaz is on her way to her sentence appeal with Will Jackson and another prison guard when the van suddenly crashes into a river due to the tyre bolts being loosened by Franky Doyle, as she thought her trial hearing was that day so she would be in the van and therefore end up in hospital in an attempt to free herself from Wentworth and prove her innocence.
At the end of the fifth season, Kaz tries Ferguson in a Kangaroo Court and regains the Top Dog position.
While I give credit to the actor playing her—there is a wildfire of crazy raging behind that woman’s eyes—the concept of "feminism out of control" is Not A Thing.
[14] Elaine Atwell, writing for AfterEllen said, "Now I gotta say, I was skeptical about Kaz’s ability to compete with the terrifying villains of seasons past.
No one could be a grande dame of infamy quite like Jaqs Holt, no one could hide madness behind such an innocent exterior like Jess, and of course we all love following The Freak down her 79-Step Revenge Plots/Fencing Regimens/JIANNA IS THAT YOU.
Atwell concluded her review about Kaz by saying, "And to make her even more dangerous, she has adopted the language of social justice in a way that has the attention of the other women.
"[15] When talking about Kaz's flashback episode, Atwell for AfterEllen stated, "Tammy MacIntosh's performance is as mesmerizing and terrifying as a wildfire, and she never lets up for a single second.
