Advancing Spaceport Development and Operations through Global Collaboration

Following the success of the inaugural International Spaceport Meeting in Milan, co-hosted by the Global Spaceport Alliance (GSA), we are proud to present the second GSA International Spaceport Forum—this time in Sydney, Australia, on the eve of the 2025 International Astronautical Congress.

The first gathering brought together participants from over 20 countries and sparked pivotal dialogue among spaceport operators and regulatory leaders, setting the stage for deeper global cooperation in space transportation. The Sydney Forum continues this mission—bringing together spaceport representatives and stakeholders from government, industry, academia, and international organizations to collaborate on the future of spaceport development and operations.

We are excited to invite you to the upcoming GSA International Spaceport Forum, taking place in Sydney, Australia, on Sunday, September 28th, the day before the 2025 International Astronautical Congress (IAC), September 29th – October 3rd.

This exclusive gathering builds on the momentum of last year’s inaugural event in Milan, which brought together representatives from over 20 countries to advance global spaceport collaboration.
