    TLAUCON25 boosts Timor-Leste and Australia trade links

    The 2nd Timor-Leste–Australia Business and Economic Conference (TLAUCON25) took place at the Dili Convention Centre (CCD), a joint initiative of the Governments of Timor-Leste and Australia, supported by TradeInvest Timor-Leste and the Timor-Leste Chamber of Commerce and Industry (CCI-TL).


    This annual conference brought together business leaders and government representatives to foster economic partnerships, promote sustainable development, and enhance bilateral cooperation in priority sectors.


    The event featured panel discussions, a trade fair, and the signing of an MoU between CCI-TL and the East Kimberley Chamber of Commerce and Industry to strengthen regional trade collaboration.


    Representing the board of the Timor-Leste–Australia Business Council (TLABC), José Teixeira addressed participants at the TLABC networking session, noting:

    • The Council’s role in advocating on issues impacting Timor-Leste–Australia business,
    • Serving as a conduit for companies seeking bilateral opportunities, and
    • Promoting private sector initiatives and sharing relevant information.


    José also encouraged Australian investors to join the TLABC and contribute to shaping its upcoming advocacy agenda, highlighting membership inclusivity for businesses of all sizes.


    He reflected on a personal connection to the venue: in 2002, as the coordinator of the transitional government restoration of independence celebrations responsible for the Restoration of Independence Trade Expo , working under the chief minister of the UN Transitional Government, José oversaw the AUSAID reconstruction of the old market (now the Dili Convention Centre) in preparation for the Expo. That historic occasion, inaugurated by Australian Prime Minister John Howard and Timor-Leste’s Chief Minister Mari Alkatiri, symbolized the enduring economic partnership between the two nations, a legacy proudly carried forward at TLAUCON25, 23 years later.
