Bastion has appointed Stefani Chinn as general manager, experience, to strengthen its integrated offering and commitment to delivering impactful, culturally connected brand experiences.
Chinn has joined Bastion as Bridget O’Sullivan commences parental leave, bringing more than 20 years of international experience building audience-led, experience-driven brands across sport, culture and entertainment.
Most recently, she led global marketing and communications for the World Surf League in the United States, with a career spanning Sydney, Singapore, Hong Kong and the US.
In her new role, Chinn will lead Bastion’s experience team, bringing her global perspective and commercial expertise to further strengthen the agency’s experiential offering. Her appointment comes as Bastion continues to invest in integrated solutions that deliver ambitious, culturally relevant experiences for clients that drive meaningful connections between brands and audiences.
“At Bastion, we’re committed to bringing together the best minds in the industry to deliver work that genuinely moves the needle for our clients. Stefani is exactly the calibre of leader who will help us do that,” said Bastion group CEO Cheuk Chiang.
“Her global experience, commercial mindset and deep understanding of how brands connect with audiences through culture and experiences make her an exceptional addition to our leadership team.”
“Coming home to Australia from the US, I can see so much opportunity for brands to build more meaningful connections with fans and audiences. Working across brand, agency and rights holder has shown me those connections are strongest when all three are pulling in the same direction, and I’m excited to bring that experience to Bastion’s ambitious, integrated team,” said Chinn.
“Here in Australia, I’m constantly reminded how central sport is to our culture and how quickly fans can tell the difference between a brand that’s simply present and one that’s part of the moment. Getting brands there is the work I love and it’s a real strength of Bastion’s.”
Chiang also acknowledged O’Sullivan’s contribution to the business as she prepares to commence parental leave.
“Bridget has played an important role in building our Experience practice, strengthening client partnerships and developing an incredibly talented team. We’re grateful for her leadership and contribution and wish her and her family all the very best as she embarks on this exciting next chapter,” Chiang added.
