Below Deck Down Under

A new charter season gets underway in Cairns, Australia's gateway to the Great Barrier Reef; the interior and exterior departments start man-down as the crew scrambles to cater to party-hearty guests.

The charter guests continue to be on edge with each other; a new stew comes aboard, giving the interior relief while captivating the deck team; a crew member over-commits to the Cancana surprise kiss threatens to ruin the party.

A complicated love triangle threatens to make things awkward on deck. The CEO is back for another round of fun. The guests have an icy request, and when a deck crew member overlooks his duties, one of the guests gets a cutting surprise.

Capt. Jason embarks across the dazzling waters of the Seychelles with almost an entirely new crew on the larger-than-life motor yacht Katina. The enormity of the boat puts new Chief Stew Lara and her interior team to the test. Chef Tzarina and Lara are reunited after a previous working relationship and tensions quickly surface as their clashing styles ignite old frustrations. Tzarina faces an infestation of weevils in the galley while she tries to find her stride with her new sous chef, Anthony.

Chef Tzarina feels the heat as Anthony begins to chafe under her direction; a near collision while docking tests Capt. Jason's patience; Lara continues to adjust to the sprawling layout of Katina; Harry finds himself in a familiar love triangle.

Harry makes his move with Brianna, but just as sparks begin to fly, he suffers an injury; Wihan ignites tension within the ranks when he oversteps Lara's department; things heat up in the galley as Anthony contemplates leaving his position.

As Capt. Jason reunites with his all-star heads of department Chef Ben, Daisy and Joao for a high-pressure opening charter with The Real Housewives of Salt Lake City, a sudden crew emergency rattles the boat before guests even board.

As housewives drama continues to boil over, Capt. Jason keeps his distance while mounting pressure in the galley puts Chef Ben and Alesia at odds. When mechanical failures, a last-minute service change and an over-the-top guest request push the crew to their limits, Alesia is left questioning whether she has what it takes to stay in the kitchen.

Capt. Jason introduces anonymous guest feedback cards and the crew celebrates a record-breaking tip. During a crew night out, personal tensions bubble to the surface when Alesia’s romantic rejection sparks fallout, and a game turns explosive between her and Chef Ben.
