Much of the fun to be had in this South Australian leg of the travelogue is surely at the expense of adorable snobs, Kevin and Janetta (pictured). Along with some of their hardier colleagues, they will endure a rustic slice of life on a farmstay. Hopefully their jangled nerves will be soothed by the refined pleasures to be enjoyed elsewhere. On the itinerary are wineries, gourmet food markets and –ooh! – a nude beach.

DATELINE: LOSING GREG: A DEMENTIA JOURNEY

★★★½

9.30pm, SBS

Reporters Naima Brown and Georgina Davies follow Greg Kelly, a 62-year-old Queensland former financial planner's quest to find a better way to cope with his early onset dementia than what is currently offered in Australia. What he discovers in Denmark is a strikingly different, infinitely more humane approach. No surprises there, but the insight that Kelly and his wife Janet give into the reality of living with this condition is invaluable. Sadly, Kelly died in February.

NCIS

★★★

8.30pm, Ten

Michael Weatherly is now so recognisable as the laddish trial scientist in Bull that it feels like a step back in time to see him return here are Washington special agent, Anthony DiNozzo. He rocks up just in time to get involved in an investigation that prompts some members to blur professional lines. The hipper cousins of this naval police team are up next, with NCIS: Los Angeles at 9.30pm.

POH’S KITCHEN

★★★½

8.30m, SBS Food Network

Loveable MasterChef alumni, Poh Ling Yeow, enlists as her guide to Darwin's culinary treasures an ABC camera operator named Elton who hails from the area and has a very cool car. Together they go net fishing for sand whiting with TV chef and local Gurindji man, Geoffrey "Jacko" Angeles, who is delightfully descriptive in his appreciation of food. The host manages to surprise him with an exotic local root vegetable.
