Rachel Horton - high school science teacher, microbiologist, Muay Thai fighter and fitness fanatic - admits she's a control freak.

That's just one reason why she'll make Queensland rugby history on Saturday when the 36-year-old becomes the first woman to referee a top-grade men's match.

Amy Perrett will be in action in the Sydney club rugby round.

At the same time as England-born Horton officiates the Norths-Bond University premier rugby clash at Courtney Oval, Australia's leading female whistleblower, Amy Perrett, makes her top-grade debut in Sydney's Shute Shield.

Although the AFL has a women's goal umpire in Chelsea Roffey and the NRL has a couple of female touch judges, Horton and Perrett will be in charge in the middle.
