GTCA was launched in January 2009 and instigated by Georgia when she was just 13 years old, six months after she was diagnosed with a rare and aggressive form of cancer.
Georgia was involved in the fundraising events up until a few weeks before she died in May 2010.
CLIC Sargent Fundraising Manager Karen Roberts said: "Thanks to GTCA and their supporters the CLIC Sargent Social Worker will be able to help children and young people with cancer, and their families, cope with the emotional, practical and financial effects of cancer, through treatment and beyond in South Essex.
"We are extremely grateful to everyone associated with GTCA for their commitment to helping CLIC Sargent provide this service for local families."
