The event, which was part of WA Day celebrations, was held at the Perth Convention and Exhibition Centre and recognised the achievements of West Australians from a broad cross section of the community.
Ms Worthington, who has worked with charities for 36 years, including the WA Make a Wish Foundation and Love Angel Projects, was celebrating her own fundraising event Buying Time for Breast Cancer Care WA (BCCWA) when she was whisked away to collect the award.
The BCCWA founder said she was overwhelmed to receive the award and working with charities was important to her.
She also thanked her family, friends and supporters who had been there for her along the way.
Other individual winners on the night included Dr Robert Isaacs who won the Aboriginal Award, Henry Boston took out the Arts and Culture Award, Peter Prendiville the Business Award, Frank Cooper the Professions Award, Andrew Vlahov the Sport Award and Rhys Williams the Youth Award.
The 10-week Buying Time campaign raised $100,000 and included an auction of an amethyst pendant created by jeweller Rohan Milne with the help of Community Newspaper Group editor Denise Cahill.
