He takes a train to the outback town of Bundayabba, where he will catch a plane to Sydney. It's very hot. Everyone is sweating, and lying languidly about. He goes to a bar full of sweaty, hugging, muscular working-class blokes who keep staring at him and grinning, and offering to buy him drinks and take him gambling.
With nowhere to go, he accepts an invitation from one of the leering, grinning men, Tim (Al Thomas), and goes back to his house for dinner, where Tim's adult daughter tries unsuccessfully to seduce him.
Later Dick and Joe, along with Doc (Donald Pleasence, Dr. Loomis in the Halloween series), take John carousing: they brutally kill kangaroos, get into a fist fight, and vandalize a pub. At the end of the evening, Doc and John have sex.
Is John horrified because he has been manipulated and seduced by the gay outbackers, or because of the recognition that he was gay all along? The association between same-sex desire and savagery is rather homophobic, but to be expected in 1971.
Gary Bond was gay in real life, the lover of future Sherlock Holmes Jeremy Brett.
