Born on 22 July, 1974, Sonija is of mixed Chinese and English parentage. Miss Kwok migrated to Vancouver, Canada from Hong Kong. After graduating from Simon Fraser University, she became a flight attendant with Cathay Pacific. After finishing her studies, she flew back to Hong Kong in 1999 and she competed at the Miss Hong Kong 1999 pageant. Before the semifinals, she was a favorite for the crown because of her looks. In the semifinal, she took the Miss Photogenic award. Having won that, she became THE favorite for the crown because in Miss Hong Kong (1996-2001), all winners of the Miss Hong Kong pageant had also won the Miss Photogenic award. Ultimately, she won the title of Miss Hong Kong (July 1999). She also bagged 2 other awards, Miss International Goodwill and Miss Intelligence. Note: Coincidentally, the winners from 1997-2000 were all hailed from Vancouver, Canada.

After winning the Miss Hong Kong title, she participated in many TVB events. In January 2000, she represented Hong Kong at the Miss Chinese International 2000 pageant in Las Vegas, Nevada. She took the crown for Hong Kong and bagged 2 other awards. She is considered one of the most successful Miss Hong Kong and Miss Chinese International winners. After her success at both pageants, she represented Hong Kong at the Miss Universe 2000 pageant. Due to her height and other factors, she failed to place in the top 10 at the pageant in Cyprus. She did make some impact though, making the top 10 of the Miss Photogenic polls.

She is currently one of TVB's leading actresses. Sonija continues to star in many TV shows, series, commercials, and entertainment functions.
