Honestly the best thing to me was the experience and catering for all ages genres and interests. It has Aussie history, wartime history, the local indigenous people, the flora and fauna of the local area. The set out of the displays were really good and suited all ages. You could easily breeze through in 30mins or take possibly 2 hours or more. You tailor the experience to suit your interests, age groups, time that you can allocate with your schedule. I’d suggest minimum 1 hour to skim through in a fast casual manner of the centre. A must see when in Exmouth.
