The Esperanza has departed Sydney. This marks the end of the Defending Our Oceans expedition - 477 days, 12 legs, thousands of miles and tens of thousands of Ocean Defenders later. In possibly the longest web article ever, we look back at the highlights of the year (well, 15 months to be exact), and thank all our Ocean Defenders for their unending dedication and support (and sense of humour) over what has been an amazing voyage.
