In July this year, Hadley told his listeners that the 22-year-old prison officer from country NSW had sex with convicted drink-drive double killer Jarad Smith in a segment calling prisons "hotbeds" of forbidden sexual relationships.

"Let me introduce you to a prisoner who is currently on day release. Jarad Smith, 23. Back in 2015, he pleaded guilty to dangerous driving causing death. His ute hit two pedestrians in Rozelle," the 2GB host said on his top-rating morning program on July 25.
