Karl's Home Town is Perth, Western Australia where he started playing competitively at age 6. By 2013 Karl had already collected world titles at ages 7, 9 and 10. Along with those titles, Karl maintained a YouTube channel which contained videos of both his tournament rounds and his training drills which built a strong following amongst both juniors and adult golfers alike. The exposure of his YouTube channel led to him being offered a full golf and academic scholarship in the US commencing when he was 11 and he’s continued living there via various scholarships since then. To date, his YouTube channel has amassed over 11 million views. Karl has signed his National Letter of Intent to Stanford University where he will start in July 2020.
