Webb has a mild form of
cerebral palsy which was diagnosed when she was two years old. Her parents did not tell her of the disability. Her cerebral palsy was diagnosed again when she won an
Australian Institute of Sport netball scholarship. AIS staff found a weakness in her right leg, which was shorter than her left leg. She was then encouraged to become involved in disability sport. She was the first torch bearer to enter the Olympic Stadium for the Opening Ceremony of the
Sydney 2000 Paralympic Games. In 2006 Katrina was selected to present on behalf of the
International Paralympic Committee to the United Nations in New York. In November 2017, Webb was inducted into the South Australian Sports Hall of Fame. Webb was appointed Deputy Chef de Mission for the
Australian Team at the
2026 Commonwealth Games. == Athletic achievements ==
