The first two major international conferences to take place at ICC Sydney will be the International Association of Restructuring Insolvency Bankruptcy Professionals (INSOL) World Quadrennial congress and the International Bar Association (IBA) annual conference, both in 2017.
Worth an estimated $17.9m (£10.6m) to the state economy, the IBA event is expected to attract 4,000 legal professionals to Sydney. The INSOL gathering is forecast to bring 800 delegates to the city and inject almost $2m (£1.2m) into the economy.
The other confirmed conferences are the 2017 AIPPI World Intellectual Property congress, the Pacific Association of Quantity Surveyors congress in 2018 and the 20th International Congress of Cytology in 2019.
Lewis-Smith said: "Four of these events are leading professional services meetings – a great alignment with the government’s economic development plan that includes a focus on the state’s finance and business services competitive advantages."
Andrew Stoner, New South Wales deputy premier, said the meetings secured for ICC Sydney would attract international delegates to the state. He added: "They will also bring opportunities for trade, investment, knowledge sharing, collaboration and innovation to our business and academic communities. It’s a win win."
