The AAO has always been a pioneer of innovative instrumentation for cosmology, and especially survey cosmology involving fiber-based massive multiplexing over large fields. I will review the instruments the AAO has developed, both for our own own use, and for other observatories including ESO, Subaru and GMT. I will also review the technologies under development by the Instrument Science group. I will also look forward to projects still in the future, and how AAO and KASI might be able to work together for mutual benefit.
