Under her leadership, Remy Ong (2006) and Jasmine-Yeong Nathan (2008) became world champions.
Singapore's bowlers have enjoyed gold-medal success at the Asian Games and the South-east Asia (SEA) Games.
While Phua has yet to come out publicly and state her intentions, sources have confirmed she will vie to be president of the Singapore Swimming Association (SSA) at its annual general meeting next month.
The New Paper reported yesterday that current SSA secretary general Lee Kok Choy will also run, throwing up the prospect of an intriguing battle for the top post in swimming in the country.
While Lee, 62, is not a household name in sport here, he has been intimately involved with swimming in Singapore and has helped revive the diving discipline.
TNP first reported Phua's link with the SSA's top post in February and I wonder what is the motivation behind her decision to throw her hat into the ring.
She is a famous face in the local sports industry and over the years, the 58-year-old has been chef-de-mission of Team Singapore at the Olympic Games and the Asian Games.
She has also been a Nominated Member of Parliament (2007 to 2009) and is a vice-president of the Singapore National Olympic Council.
But, her only genuine role in swimming here so far has been as a parent, with two daughters who used to swim competitively. Phua fixed Singapore bowling, but she holds no magic wand.
It is not as if Singapore swimming is in desperate need of major surgery and should turn to someone from the outside to radically shake things up.
Current SSA president Jeffrey Leow will vacate his post next month because the constitution of the national sports association (NSA) only allows for a maximum eight-year term.
