Development of a 10GW-plus portfolio of offshore wind farms – most of it floating and some a replacement for exiting coal power – is being explored off Australia and New Zealand by a company co-founded by executives who launched the pioneering Star of the South project.

Oceanex Energy is looking at advancing gigawatt-scale projects off the Australian states of New South Wales, Western Australia and potentially Queensland, as well as neighbouring New Zealand, under a portfolio that could underpin massive expansion of wind at sea off the two nations starting in the late 2020s and continuing throughout the 2030s.
