Wilks' TV career began on the Nine Network replacing Tracey Dale on the Nine Network lifestyle series Our House in February 1998.

That year Wilks became the first woman to host two prime-time shows on Australian television in the same year. In 1999, she dropped her Our House commitment to focus solely on Changing Rooms. That success continued through into 2001 with the series spinoff Changing Rooms Special Operations and concurrently a new series Guess Who’s Coming to Dinner which ran for one season. After an eight-year run on Changing Rooms, Wilks resigned to return to her home town, Melbourne. She then hosted ‘Body Work’ for the Nine Network, which won its weekly timeslot.

She was a celebrity contestant on the Seven Network's Dancing with the Stars. She also won her episode of the 2008 series The Singing Bee and made two appearances on Network Ten's Thank God You're Here as an ensemble cast member. During the years 2006–2008 Wilks broadened her media experience with a weekly radio showLunch With Suzie Wilks on Melbourne radio's 3AW. In 2007 she accepted a speaking part on the Australian movie December Boys alongside popular English actor Daniel Radcliffe. Wilks maintains a portfolio of several national and local product endorsements and in the past has featured in TV and press advertisements for Holden cars and Cadbury chocolates. She is currently the face of the Australand property group and is signed to Solomons Flooring with The Suzie Wilks Collection of carpets. In 2009 she co-authored a book called 'RUEA?'
