The ROTORTECH Helicopter and Uncrewed Flight Exposition is the premier industry event for the Helicopter/Rotary Wing and RPAS/UAV/eVTOL community in Australia, New Zealand and the Indo-Asia-Pacific region.
Held by AMDA Foundation with input from major industry supporter the Australian Helicopter Industry Association, ROTORTECH 2024 will provide a vital interface between industry, regulators and government, including:
- Operations and safety presentations
- Industry conferences
- Manufacturers technical workshops
- Industry exposition showcasing the products and services of helicopter and uncrewed flight related companies
ROTORTECH 2024 will host conferences by the AHIA and Australian Association for Uncrewed Systems (AAUS) and feature presentations by key rotary and uncrewed flight industry experts from Australia and the Indo-Asia-Pacific region.

The second Advancing Earth Observation Forum will be held at the Adelaide Convention Centre. The five-day event will attract delegates across a broad spectrum of applications, sensors and interests, including industry, research, defence, government, students and end-users.
The biennial Forum was created to enable the Earth observation (EO) community to communicate, coordinate, collaborate and collectively assess the state of EO in the Australian and Asia-Pacific region.
AEO24 will build on the momentum generated at the inaugural AEO Forum held in Brisbane in 2022, bringing together all sectors involved in EO to propel the sector forward to meet the growing international demand for EO.

The 9th International Colloquium on Scientific and Fundamental Aspects of GNSS will bring together members of the European scientific community and their international partners involved in the use of Galileo and other GNSS in their research.
The colloquium will address several major areas of research:
- Scientific applications in meteorology, geodesy, geodynamics, geophysics, space physics, oceanography, land surface and ecosystem studies.
- Scientific developments in physics with a potential impact on future GNSS, particularly in testing fundamental laws of physics.
- Aspects of metrology such as reference frames, on board and ground clocks, precise orbit determination and time and frequency transfer.
- Scientific aspects of satellite navigation, positioning and its applications.
- Other topics of interest such as big data, IoT, novel disruptive technologies, Cubesats, HAPS, UAVs and autonomous vehicles.
- Systems and technologies for navigation in space.

In celebration of the International Day of Women and Girls in Science, Earth Observation Australia will conduct a special webinar that will shine a spotlight on the role women play in Earth observation (EO) science and technology.
This webinar will explore the journeys of women who have overcome challenges to lead ground-breaking work in EO science. The session will highlight their achievements, the barriers they’ve faced, and the importance of mentorship and collaboration in empowering the next generation of women scientists. Attendees will gain insights into fostering inclusive networks and strategies to support women in leadership roles within this critical field.

Held every three years, the European Space Agency (ESA) Living Planet Symposium brings together diverse communities with a common interest in using Earth observation data, in a forum to meet and network with space professionals from a wide range of sectors.
Living Planet Symposium 2025 will have an emphasis on transitioning from ‘Observation to climate action and sustainability for Earth’.
The event will provide a forum to discuss the latest findings and applications based on satellite data, and to review the contribution that data and technologies have made and could further make in addressing environmental and societal challenges.
The symposium will also provide a chance for showcasing innovative products, services, missions and initiatives, with the overarching goal of demonstrating how science, society, policy-making, businesses and the economy can all benefit from observations made from space.
