Having the support of many returning and new partners in 2021, Stewart was excited to see all parties support WAU on its journey back to the top.
"It's great to get the Mobil 1 Middy's Racing car out there for everyone to see, we love the way it looks, even standing still," Stewart said.
"To have so many returning partners back with us for another year is reflective of their support and loyalty, and we can't thank them enough.
"It's also amazing to be able to welcome six new partners to our team and business this year, who will all play a part in our journey; we welcome them with open arms to our family."
Fullwood will debut the new livery at a rookie day at Winton on Wednesday before next month's Repco Mt Panorama 500. Tickets are on sale now.
