In this paper we report on a 6U CubeSat named Waratah Seed-1 designed by the ARC Training Centre for CubeSats, UAVs, and their Applications (CUAVA) under the Waratah Seed project. Waratah Seed is a pilot Space Qualification Mission initiated by the NSW Governments Space Industry Development Strategy with partial funding from Investment NSW. The goal of the mission is to give NSW and Australian space industry groups an opportunity to test their technology in space by flying on a 6U ride-share CubeSat. This project is first of its kind in Australia, allowing space-tech start-ups and other groups to access a satellite spaceflight to test payloads at an inexpensive rate and in a more accessible way. The mission will help overcome one of the key barriers to gaining space flight heritage and should help accelerate the development of the Australian space ecosystem. There are two ways that payload teams can join: either via the WS-1 Payload Competition, where start-up companies and academic teams compete for heavily subsidised ride-share slots; or as a commercial client. Half of the satellite’s volume (3U) is allocated for commercial clients, with the other half split equally between the payload competition winners and the satellite bus. The design of the WS-1 Satellite bus is based on its predecessor, the 3U CUAVA-1 CubeSat, and its sister 6U spacecraft CUAVA-2.
