This tactical STI campaign using OOH at Perth Airport’s Arrivals and Departures encouraged safe sex practices when travelling and getting tested on return. The challenge was to use clear language while also considering that children and the vulnerable would see the posters. The solution was to redesign retro baggage tags that allowed us to subtly build in the messaging. We also adjusted the messages for each placement. “Practice safe sex while you’re away” in Departures, and “Get tested” in Arrivals, because there are some souvenirs from a good trip that you don’t want to bring back.
