Crime by Jason Walls Premium Content  DARWIN'S "world record" wanker Gary Chisholm is back up to his old tricks after admitting to fondling himself while watching two teenagers at the Casuarina nudist beach in 2019. The 47-year-old pleaded guilty in the Darwin Local Court to gross indecency in a public place after "gripping, pulling and flicking his erect penis" behind the women on August 25. The court heard a man noticed what Chisholm was doing and told him to stop before an argument ensued and he went and called police who caught Chisholm "in the act". The 38-year-old man, who the NT News has chosen not to name, came to court to deliver his victim impact statement in person, saying "nobody should be made to feel uncomfortable" on the public beach.
