Marianna Tolo made the move from North Queensland to the AIS in 2006 to begin her basketball journey.
After impressing in the WNBL this led to national team attention, representing Australia at the 2007 FIBA Under 19 World Championship, 2009 FIBA Oceania Championship and 2009 World University Games, as Tolo became a regular in and around the Jayco Australian Opals setup.
Playing with the Canberra Capitals she won two WNBL Championships, and earned a spot in the 2010 FIBA World Championship squad.
Marianna headed overseas to take up a contract with French team Aix-en-Province in 2012 where she has quickly established herself as top 5 scorer and top 10 rebounder. It was another successful season in France in 2013/14 with Bourges Basket, reaching the LFB French League Finals and Euroleague semi-finals.
