In 1978, Hanson (then Pauline Zagorski) met Mark Hanson, a tradesman on the Gold Coast. They married in 1980 and established a construction trades business, specialising in roof plumbing. Hanson handled the administrative components of the company, similar to her work with Taylors Elliotts, while her husband dealt with practical labour. In 1987, the couple divorced and the company was liquidated. She moved back to Ipswich and worked as a barmaid at what was then Booval Bowls Club. Hanson then bought a fish and chip shop with her then-business partner Morrie Marsden. They established the holding company Marsden Hanson Pty Ltd and began operations from their recently opened fish and chip shop in Silkstone, a suburb of Ipswich. Hanson and Marsden both shared the administrative responsibilities of the company, but Hanson took on additional practical responsibilities, including buying supplies and produce for the shop and preparing the food, which was among many things that contributed to her notoriety during her first political campaign. Over time, Hanson acquired full control of the holding company, which was sold upon her election to Parliament in 1996.
