The Global Sustainability Coalition for Open Science Services (SCOSS) plays a unique role in assessing essential open infrastructures that need community funding and recommending them to potential supporters. Each year Open Access Australasia holds a webinar for members to inform them of the current initiatives. This webinar introduces the SCOSS family of open infrastructures, featuring the latest members: the Research Data Alliance and Software Heritage. Liz Walkley-Hall, who serves  on the SCOSS board as CAUL representative, is joined by Rosalie Lack, SCOSS Coordinator, Morane Gruenpeter (Software Heritage) and Hilary Hanahoe (RDA)
