He is a firm boss, and expects someone to do what he has asked them to do. Mick asked Zac to take his turn at the sea patrol to prevent Zac from having a heatstroke, and he didn't want to hear about any deal Zac and Cam made. Once a kid had a heatstroke on the beach, and Mick asked Cam to get some ice, and when Zac offered to bring it, he refused the offer, and wanted Cam to do what he asked. After Zac had rescued a girl from drowning, Mick congratulated him on a job well done.
He has a son named Ned.
