The Best Aquariums in Western Australia
How this list is ordered: by how complete our listing is — how much we hold on opening hours, ticket prices, accreditation, photographs, animals and facilities. It is a measure of our own coverage, not a judgement of the venue. We hold no visitor scores or conservation assessments, so “best” here means every aquarium in Western Australia that qualifies for the list, fullest entry first.

Our ranking methodology
This is not a ranking. The 2 venues above are listed alphabetically by name, the same order used throughout this site. We do not collect visitor reviews, star ratings, ticket-sales figures or a conservation-impact score, so none of those exist here to rank by — “best” in this page’s title means every venue that qualifies for this list, not first-to-last by quality. If we ever add a data source robust enough to support an honest ranking, this note and the order above will change together.
