Despite her youth (she was 15 in 2011), Larissa was successful in her quest to become a professional soccer player. With half a dozen goals to her credit in the national titles in Adelaide, the teenager striker from Tewantin earned her way into the under-19 Australian Schoolgirls football team. A student of Kawana Waters State College Football School of Excellence, she was able to secure this coveted position for the second time. She was even brought into the side in 2011's women's world cup, only when she was 14 years old.
In 2011 she helped her club side Peninsula Power FC to triumph in the premiership by scoring 12 goals.
