An extra 40,000 free tickets have been released for the Optus Stadium Open Day after the initial allocation of 70,000 sold out within less than two hours.
The open day will take place on January 21 and will give attendees the chance to explore the features of the new 60,000-seat stadium.
Premier Mark McGowan said the demand for tickets to the open day had led him to approve new morning sessions being added to the event's schedule.
"This world-class stadium belongs to the people of Western Australia and demand for the open day today has been exceptional," he said.
"I am delighted that even more people will now have the chance to see inside the stadium for the very first time."
Ticket holders will be able to browse and explore the features of the stadium and experience firsthand the 'fans first' facilities that have been integrated into the design.
The Stadium Park precinct will also be filled with a range of free family activities, entertainment, food and live music.
Each session throughout the day will also feature a stunning audio-visual experience incorporating the stadium's two giant screens.
The additional tickets will be available from 10am Friday at www.perthstadium.com.au
The stadium will host its first sporting event on February 10 when the Fremantle Dockers womens' side take on Collingwood in the AFLW.
