Before entering politics, Zanow was the owner of Zanow's Concrete and Quarries, a concrete business founded by his father Viv.[1][2] Zanow owned quarries in Coominya, Fernvale and North Booval, which were all damaged in the 2011 Queensland floods.[3]
He was also the president of the Ipswich Show Society.[4][5]
On 16 April 2024 − the day he was formally sworn into parliament − Zanow was diagnosed with Microvascular Ischemic Disease, an incurable brain disease.[8] He made his diagnosis public on 12 July and announced he would not contest the 2024 Queensland state election in October.[9] The division was subsequently won by Labor, despite the election of a Liberal National government.[10]
