Marcus was in the ocean as soon as he could swim as a child where he would boogie board and surf regularly as a grom off Cronulla Point. This love for the ocean and the environment leads him to learn to scuba dive with an AOW certification in Jervis Bay at 16 years of age.

Armed with an Accounting Degree, he works weekdays in the corporate world to pay the bills for his dive addiction, as his real hobbies are teaching scuba diving on the weekends and dive travel to remote destinations.

Over the last 7 years Marcus has annually migrated to the Philippines exploring the variety of diving there, from the Thresher sharks of Malapascua to the WWII shipwrecks of Coron. The most unique dive he has done recently was in Silfra Iceland, diving in a lake surrounded by snow, ice and active steaming geysers between two tectonic plates where it was -2 degrees Celsius in the water and -7 degrees on the surface (thank goodness for dry suits and hot chocolate).

After going through the Abyss internship, he started working part-time as a Dive Master for Abyss in 2017 and progressed to OW Instructor in 2019, then Master Scuba Diver Trainer in 2020. He has also worked on the Mike Ball live aboard Spoilsport in the Great Barrier Reef. His Favourite course to teach is wreck, his favourite critter is the Seahorse at Bare Island "Golden Boy", his dive buddy says he spends way too much time looking at cephalopods, and he always watches reruns of David Attenborough's Blue Planet 2.
