Garth first started his electronic dance music (EDM) career in London, United Kingdom in 1993. Returning home, he expanded his operation into The Event Network Australia predecessor organisation, Smile Police Productions.
Garth was instrumental in running some of Melbourne legendary dance music nights. He was also managing the alternative lifestyle and music festival Rainbow Serpent from 1999 to 2012. Garth grew the fledgling World Vegan Day festival from 80 patrons at Albert Park Lake to over 20,000 thousand of participants – now the third-largest Vegan-themed festival worldwide and the largest in Australia.
Garth also consults or co-manages numerous other workshops, sporting, music, and special interest events around Melbourne and Australia.
