Experience the VERTIGO at Optus Stadium, where sports enthusiasts can step off the roof and walk out on a platform that extends beyond the edge of Australia's third-largest stadium. With no handrails and harnessed from above, the more adventurous can push their senses to the limit and dare to lean and look down over the edge! Gulp. The western viewing deck at Optus Stadium, also known as Perth Stadium, offers uninterrupted views of Perth and the Derbarl Yerrigan (Swan River). This fully accessible rooftop experience provides incredible views of Perth and the hallowed Perth Stadium turf. The new VERTIGO structure, weighing 70 tonnes, was built off-site in 15 modular sections and craned into place during an operational stadium calendar that included three AFL finals, including the AFL Grand Final.
