The Timor-Leste–Indonesia–Australia Growth Triangle (TIA-GT) is a combined initiative of the regions of Eastern Indonesia, Northern Australia, and the Democratic Republic of Timor-Leste.
The Indonesian government believes that the initiative would provide an opportunity to develop and economically strengthen the Eastern regions of Indonesia.
The Australian government cites benefits of diversifying the country's mining-based industry and bringing positive development to the Northern city of Darwin and surrounding areas.
Timor-Leste sees the potential to become a manufacturing and logistic center for raw materials and semi-processed products of the surrounding Indonesian islands.
[3] In April 2011, former Chief Minister of the Northern Territory of Australia Paul Henderson expressed interest in being involved in this initiative.
[3] In March 2016, representatives of all three countries met and discussed a "tourism path" between Bali and Darwin, which would lead through islands of Flores and Timor and bring an economic boost to all three nations.
In July 2018, Australia expressed support for Timor-Leste's intentions to join both ASEAN and the World Trade Organization (WTO).
ASEAN's members include Malaysia, the Philippines, Singapore, Thailand, Brunei, Vietnam, Laos, Myanmar, Cambodia, and Indonesia.
