Cruise 1323 is one of Adelaide's longest-running radio stations, with a history spanning over 80 years. Originally launched as 5DN in 1924, it was the first commercial station to begin broadcasting in South Australia. The station has undergone several transformations over the decades, including a brief stint on FM in the 1990s.

In 2005, the station rebranded as Cruise 1323, adopting an easy listening and classic hits format targeting Baby Boomers. Cruise 1323 plays a mix of music from the 1960s to the 1980s, with a focus on providing "more music and less talk" throughout the day.

The station's current lineup includes veteran broadcaster John Dean hosting the morning show from 7 am to 12 pm on weekdays. Cruise 1323 continues to be a popular choice for Adelaide listeners seeking nostalgic hits and easy listening music.
