The fourth season of the Australian drama Sea Patrol began airing as Sea Patrol 4: The Right Stuff on 15 April 2010. Most regular cast members have returned.

Other non returning cast members included Jeremy Lindsay Taylor (Buffer), whose position has been filled by Conrad Coleby (Dutchy) and Jay Ryan (Spider), replaced by Danielle Horvat (Bird).
