The dress up idea was originally introduced by Netball NSW in 2011 as a fun and easy way for players, umpires, officials and spectators to dress up and fundraise for The Kids’ Cancer Project without impacting playing uniforms or disrupting play.
In 2018, NSW Rugby Union accepted the challenge to get their clubs involved with their own Crazy Hair & Sock Day to raise awareness and funds for childhood cancer research with all proceeds going to The Kids' Cancer Project.
The Kids' Cancer Project has a special association with NSW Rugby Union. Owen Finegan, CEO of the charity is a retired Australian International Rugby Union player. He was a key performer for the ACT Brumbies from their inception in 1996, joining from Randwick Rugby Club. Finegan played in 90 Super 12 matches for the Brumbies and was one of three remaining foundation players in the 2005 squad. He helped them to two titles, including captaining them to their 2004 triumph, and scoring a Super 12 record - 31 tries for a forward.
He made his international debut against Wales in 1996 and went on to win 56 caps despite having ankle and knee reconstructions, plus operations on both shoulders. He was an integral part of the Wallabies’ success over following decade and was named in the Wallaby team of the first professional decade in 2005.
The undoubted highlight of Finegan's career came in 1999 when he scored an injury time try as Australia won the Rugby World Cup.
