Sun Park-Pezzimenti is a Korean-born Australian singer, actress, entertainer and former member of the children's entertainment group Hi-5 as well as the television series of the same name. She achieved her first successful career move to popularity in 2007, at 26, when she was originally hired as a temporary replacement for Kathleen de Leon Jones, who went on maternity leave. However, in July 2007, Kathleen announced that she would not be returning, in order to devote her time to raising a family. Therefore, Sun took over her place permanently.
Sun 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 confirmed she would not be returning to the group.
In December 2008, Sun announced that she would be leaving Hi-5 after 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. Sun's final performance with the group was at the 2008 Carols by Candlelight.
As an actress she appeared in the 2007 Australian movie The Jammed, and stars playing the main role of Rubi, a young girl that had moved from China to Melbourne and found herself a victim of the Victorian sex slave trade. She worked alongside Emma Lung and Saskia Burmeister in The Jammed. The film received mainly positive reviews, and was nominated for many Australian film awards along with the actors. She has also appeared many other Australian shows.
Sun 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.
Sun is a kid's entertainer, but other than Hi-5, she seems to specialise in funk, rock, jazz and hip hop fusion. As she has performed and worked with the Rogue Traders before, it can also be assumed that she partakes in contemporary rock as well.
