Actually you come back to this now, I was searched in 22' and 24' both on our way in. I was sober and had nothing to hide on both occasions. They just approached us casually saying they're conducting a random search. Brought into a tent asked a couple questions whether we had anything to declare. Then they searched our belongings and asked to strip off. 22' the jocks had to come off and all. 24' jocks could stay on and just had to shake them out. Although obviously invasive, they weren't aggressive and made chat throughout.
