OA Collective nabs Cartology talent for agency sales role
Out-of-home (OOH) company OA Collective has appointed Cartology’s Ashleah Harding as its new agency sales director (Southern states).
Harding joins after three-and-a-half years at Cartology, where she was head of agency sales for Vic, SA, and WA. Prior to that, Harding was head of retail and food at Nine, and has further experience at Fairfax, carsales.com.au and Network Ten.
In the new role, Harding will help drive growth and expansion for OA Collective. The recently-launched OOH player describes its model as “transformative”, as it empowers independent OOH owners by consolidating them under one roof.

“I am incredibly excited to be part of a business that is reshaping the OOH landscape. OA Collective is at the forefront of championing independence in the out-of-home sector, uniting independent OOH owners to offer advertisers unprecedented access to a network of premium assets,” Harding said of her appointment.
“Our collaborative network continues to grow and deliver mass scale and simplicity demanded by brands, enabling impactful campaigns that drive tangible results.
“Our focus is to unlock new opportunities for independent OOH owners through a collaborative network that facilitates large-scale advertising solutions. This approach ensures that campaigns are straightforward, compelling, and designed to drive consumer engagement and purchase.”
OA Collective’s co-founder, Grant Kirkby, said: “Ashleah’s appointment signifies a pivotal moment for OA Collective as we continue to drive rapid growth in our business and expand our OOH network, particularly across the critical southern region.
“Her role is focused on delivering excellence through market-leading OOH media campaigns across our newly established network of premium independent out-of-home assets across Australia and New Zealand.”
OA Collective is one of four new members to the Outdoor Media Association (OMA), announced last week.
