Without Limits: Australia, BBC1, 8pm

FOLLOWING critically acclaimed series Without Limits: Vietnam, and to mark the 2018 Invictus Games in Sydney, this two-part observational documentary sees a team of injured British and Australian veterans embark on an extraordinary 1000-mile expedition across the Kimberley, the northernmost of Western Australia’s nine regions. The Kimberley is three-times larger than England but with a population of fewer than 40,000, and the team’s route follows the Gibb River Road, an old stock route of mostly unpaved road. This 400-mile track is one of the Kimberley’s main attractions and will take the adventurers from Derby on the west coast to Kununurra (or Wyndham), through a spectacular landscape of intensely coloured ranges, dramatic gorges and lush rock pools and waterfalls.

The Parachute Murder Plot, STV, 9pm

THE case of an army sergeant who attempted to murder his Scottish wife by tampering with her parachute was one of the most disturbing of recent years. Emile Cilliers sabotaged the equipment that he knew his wife Victoria, an experienced instructor, was going to use, but she survived the 4000ft fall in Wiltshire on Easter Sunday 2015, thanks to the soft soil she landed on and her light weight. Cilliers, who was plagued with debt, had hoped to cash in on his wife’s life insurance payout to start a new life with his lover. However, he was jailed for life and told by a judge at Winchester Crown Court that he must serve at least 18 years. In this documentary, Fiona Bruce looks back at the case, analysing previously unseen police tapes and speaking to some of the people directly involved.
