IMOS Funding: • $50 M cash from Commonwealth • Additional $40 M cash and in-kind support from marine agencies around Australia IMOS Development: • National Science Plan priorities workshopped in 2006 • Local science plans (with equipment needs) developed • Envelopes for equipment allocations developed • Agreement of who runs what facilities and what “nodes” are allocated facilities. • Plan strongly supported and funded by Aust. Govt. National Collaborative Research Infrastructure Strategy
