Merlin Entertainments Group has completed the acquisition of Sydney Attractions Group and Kelly Tarlton's Underwater World from Village Roadshow.

The AU$115m (US$114m, £73m, 85m euro) deal, announced in December 2010, includes Sydney's top three tourist attractions - Sydney Aquarium, Sydney Wildlife World and the Sydney Tower Observatory and Skywalk, as well as Manly Oceanworld in Sydney, the Hamilton Island Wildlife Park in Queensland and Kelly Tarlton's Antarctic Encounter and Underwater World in Auckland, New Zealand.

Merlin will undertake a multi-millon dollar investment programme for the six attractions and the company has appointed Edward Fuller as divisional director to manage the new Australia/New Zealand 'midway' division.

Fuller said: "These are exciting attractions with enormous potential. They are well established and of a very high quality, and I believe will benefit greatly by being part of the Merlin 'family'.
