In episode 4, the crew looks at how Australia treats its Indigenous population and the often volatile relationship between black and white. Joe, Amer, Radhika, Gurmeet and Mahima start at the place Indigenous people first came into contact with white people, Sydney's Botany Bay. It's a good step-off point... leaving the Indians wondering what state the relationship is in after 200 years of white settlement. From there, the road-trippers head to Moree in northern NSW, infamous as one of Australia's last bastions of legislated racism. The group visits Moree Baths, where Charles Perkins campaigned for Indigenous people to be allowed to swim in 1965. At the time the issue divided the town's black and white populations. Does that divide still exist? Joe takes the question to local Indigenous elders and to Moree's Mayor, Katrina Humphries... From Moree to Australia's red centre, Alice Springs. The crew visit the Todd River where Joe explains the damage Indigenous alcohol abuse has caused here. Suddenly the group realises members of the local community are upset by their presence... the situation becomes tense as two women begin throwing stones. It's a confronting experience and one that has the team running for cover.
