Nova 100 commenced on the Melbourne airwaves on Monday 3 December 2001 with Kate Langbroek being the first voice heard on the station. It was the first new commercial radio station in Melbourne for 21 years.
The station is a major player in the Melbourne radio market, challenging the Southern Cross Austereo station Fox FM for the number one market position playing alternative, hip hop, pop & dance music, with a strong lean towards new music. However in recent years it has failed to offer much competition, failing to come close to Fox FM in the ACNielsen ratings.
Hughesy, Kate & Dave was the inaugural breakfast show with Dave Hughes, Kate Langbroek and Dave O'Neil. Dave O'Neil later resigned and moved to Vega 91.5 in July 2006. Both Dave Hughes and Kate Langbroek remained with the station until November 2013. In December 2013, Meshel Laurie and Tommy Little replaced Dave Hughes and Kate Langbroek with their new show Meshel & Tommy.
In 2010, Nova announced that it would remove their policy of "never more than two ads in a row" by increasing the number of ads broadcast per hour from 12 to 21 during the peak times of breakfast and drive.
Nova 100 operates on the 100.3 MHz FM frequency from the TXA Obseratory Rd tower on Mount Dandenong. The transmitter is a Broadcast Electronics FM 10S with an FXi digital exciter. Its transmitter power is 9.5KW which gives a 56 kw ERP.
