The Friends of Geelong Botanic Gardens (FGBG) is a self-funding, voluntary association formed in 1985 to "conserve, protect and enhance the Geelong Botanic Gardens..."

FGBG aims to promote community awareness and appreciation of the Geelong Botanic Gardens and support the Gardens as a centre for education, scientific research, horticulture, conservation and recreation.

FGBG acts in partnership with Gardens' management to develop and support the GBG and Eastern Park. FGBG provides information, education, interpretation and relevant public programs.

A voluntary guiding service interprets the Gardens for the public. Guides are trained to provide a diverse range of Gardens' experiences for individuals and groups. Friends manage and support the development and implementation of programs for primary, secondary, tertiary and community education.

Friends manage the FGBG/Botanic Gardens Reference Library. Friends provide a range of publications - a newsletter, information sheets, brochures, flyers etc.

Friends encourage and support cultural, artistic, environmental and horticultural events.

The Friends Nursery, with a group of Growing Friends, select and propagate plant material for sale, maintain a stock management system, maintain a perennial border and co-operate with the Heritage Rose Group.

FGBG manages the Friends Teahouse, providing light refreshments, run by employed staff and volunteers. Founded in 1985 the Friends are a volunteer support group working in partnership with the Geelong Botanic Gardens.
