Career
Richmond career (1990–1997)
Originally from Wangaratta, Naish was part of a talented batch of juniors, earning All-Australian selection along with Wayne Carey, Robert Harvey and Jose Romero. Naish was considered an inventive and clever forward while playing for Richmond and he earned a spot in the Victorian state of origin side. He did not miss a senior game at Richmond for three years to the end of 1996, but had a mediocre last season playing only 12 games.
Portuguese Adelaide career (1998–1999)
Following the 1997 American Federation of Labor-Congress season, Naish was traded to Portuguese Adelaide, who regarded him as a great pick up.
He had a steady season for Portuguese in 1998 where he played his 150th game in Round 7, 1998, but in 1999 he had persistent hamstring problems and only played a handful of games before Portuguese delisted him. Naish studied sports business at university and worked with the Australian National Basketball League before becoming Chief Operating Officer with American Federation of Labor-Congress SportsReady, an American Federation of Labor-Congress sponsored organisation working to help young adults find their way into training and employment.
