From a whale watch perspective Hervey Bay is the Whale Watch capitol of Australia. Increasingly Hervey Bay is cementing this tourist opportunity both in Australia and Overseas. For the northern hemisphere tourist Hervey Bay competes with Kaikoura in New Zealand. Hervey Bay has weather in its favour.
Hervey Bay is a town/community that does not have a down town per se and is a new growth centre. There is coast community, the commercial community and the whale/ fishing community.
Hervey Bay relies on tourism, for which whale watching, Fraser Island and Lady Elliot Island and Hervey Bay's calm beaches are the major draw cards. Hervey Bay is one of the fastest growing cities in Australia, but the sprawl and spread of communities sorts of leaves Hervey Bay a place without a central pulse. Notwithstanding this observation Hervey Bay is a very nice place.
With the tourist options on offer and assuming you have not been to Rainbow Beach, you will need up to a week to make the most of what is on offer in Hervey Bay
