A gigantic 7.4 metre Great White Shark replica 'floats' into Sydney Harbour on November 26, 2013 as it returns from Melbourne after being away for over a year. The replica shark was making its way to SEA LIFE Sydney Aqarium where the 'Shark Mission' exhibition is due to open on December 21, an immersive experience which aims to educate people about the plight of the world's most misunderstood predator and provide expert information on shark habitats and behaviours.
