"Below Deck Down Under" is back with an epic new season, featuring the return of Capt. Jason, Chef Tzarina and Deckhand Harry. This season the crew sets sail to a stunning first-ever series destination - the pristine turquoise waters of the Seychelles off the coast of Africa. Jason is at the forefront of Motor Yacht Katina, the franchise's largest vessel yet. With clashing department heads and hard-to-entertain guests, he must explore new depths to face this season's challenges.

Now in the galley of her dreams with a sous chef by her side, Chef Tzarina is ready to explore the vibrant flavors of East Africa. However, a weevil infestation and rising tension with her sous chef threaten to turn her kitchen into chaos. New Chief Stew Lara excels at keeping her department in tip-top shape, going to great lengths to make sure her guests have a spotless experience - even if it means scaling four flights of stairs for every service. Amid a series of on-deck blunders leading to a jet ski accident that ends in a hospital visit, Bosun Wihan faces an uphill battle to keep team morale afloat. The interior runs like a well-oiled machine until one stew's request for more responsibility rocks the boat.

Captain Jason and Chief Stew Aesha reunite for an unforgettable, full-throttle charter season with a lively new crew and wild guests in the stunning waters of Cairns, Australia - the gateway to the Great Barrier Reef.

Jason is at the helm of the vintage M/Y Northern Sun, where he navigates tumultuous crew dynamics and unprecedented shake-ups throughout the season. Each charter includes nonstop adventure and breathtaking underwater sight-sea-ing, but unruly guests break Jason's rules, putting their holiday in jeopardy. Now a more seasoned leader, Aesha takes on some of the biggest obstacles of her career while looking out for the crew's well-being. Mouth-watering menus and flavorful spreads delight the guests, but frustrations simmer between Chef Tzarina and Jason when he assists in the galley.

Initially understaffed, the deckhands make costly errors as they struggle to find their stride on the unpredictable, aging vessel. The interior experiences smooth sailing until a clash of work styles creates a rift between the stews. Unexpected newcomers rock the boat throughout the season, including a shocking franchise crossover with the arrival of a polarizing familiar face. A slew of hook-ups, break-ups, and a rare "love pentagon" leaves the crew reeling as tension spills over on deck.
