GTB is built on the hard work and accomplishments of the two institutes that existed before 2008, namely, the Gestalt Association of Queensland Inc. and the Brisbane Gestalt Institute.
The Brisbane Gestalt Centre was established in 1980 by Yaro Starak, and in partnership with Maria Vogt it developed into the Brisbane Gestalt Institute (BGI).
The Gestalt Therapy and Training Centre established by Mac Hamilton offered its first program in 1991. In 1997 the Centre was formed into an Incorporated not for profit Association, the Gestalt Association of Queensland Inc. It offered higher education programs accredited by the Minister for Education Queensland from 1997, namely a Graduate Certificate and a Graduate Diploma. It received accreditation to deliver a Master program in 2004.
In 2008 the Gestalt Association of Queensland Inc and the Brisbane Gestalt Institute merged under joint ownership of Dr Greer White and Maria Vogt and created Gestalt Therapy Brisbane Pty Ltd.
In 2014 GTB received re-accreditation and re-registration to deliver its Master of Gestalt Therapy and Graduate Certificate in Gestalt Therapy for a period of 7 years from the Tertiary Education Quality and Standards Agency (TEQSA). GTB also received accreditation of its Master of Gestalt Therapy from its professional associations, Gestalt Australia and New Zealand (GANZ) and Psychotherapy and Counselling Federation of Australia (PACFA).
