Sun Park

Park graduated from the University of Texas at Austin with a Bachelor of Business Administration, Finance. She later appeared in the Brisbane and Sydney seasons of Mamma Mia!. Before her stint with Hi-5, she toured with the live act BPM - Beats Per Minute that fused funk, rock, jazz and hip hop music, and worked with the Australian band Rogue Traders, alongside the now very successful Natalie Bassingthwaighte.

In 2006, she was hired as a temporary replacement for entertainer Kathleen de Leon Jones in the children's entertainment group Hi-5, and was announced as a permanent replacement in 2007 when de Leon Jones confirmed she would not be returning to the group. In December 2008, Park announced that she would be leaving Hi-5 after less than three years with the group in order to concentrate on settling down and starting a family. She also expressed that she felt she was only ever meant to be a temporary replacement for Kathleen. Park's final performance with the group was at the 2008 Carols by Candlelight.

Park told the media in 2008 that she was going to settle down and focus on starting a family after finishing her work with Australian children's entertainment group Hi-5. She announced plans to marry in 2009 and that year, she married business development worker Nathan Pezzimenti.
