Latest: oOh!’s newest digital billboard in the Perth CBD. Now over 260 screens across Australia. This large format site is oOh!’s third in the CBD. It really re-enforces their OOH pre-eminence in Perth. Elder St is west facing and captures east bound traffic from Subiaco and West Perth on to the Freeway South entrance, as well as Elder St traffic heading towards St George’s Terrace. oOh!’s network continues to expand nationally, in retail centres, airports, office towers, cafés, gyms, venues and universities.
