She rode in the series last year and won the Listed Brisbane Handicap (1600m) on Cantbuybetter for Currie.
Cantbuybetter will be having another attempt at the race but will be ridden by Jeff Lloyd.
However, Kah will rode French import Kay Kay Boy for Currie.
After racing without a win in France, Kay Kay Boy has won four of his seven starts for Currie.
Kah has rides in all five Origin heats but has picked up several other mounts during the two days.
“Ben was a great supporter of mine and helped me get a profile in Queensland when I won on Cantbuybetter last year,” Kah said.
“I was more than happy to ride Kay Kay Boy who is a horse on the up.”
Kah recently rode her 700th winner in just over six years in the saddle and is in constant demand.
“I am off to New Zealand next week to ride in a jockeys challenge. I like the Origin concept because it gives you a chance to line up your ability against jockeys from all over Australia and New Zealand,” she said.
Kah says she is asked almost weekly if she has any plans to move interstate in the coming years.
