Make sure you pack your binoculars as Western Australia is a haven for whale watching tours.
There are many whale-watching cruises available as well as plenty of land-based lookouts.
Top vantage points and charter vessels can be found in Albany, Broome, Exmouth, Perth, Fremantle, Hillarys, Denham, Kalbarri, Geographe Bay and at Rottnest Island.
In Western Australia you're most likely to spot a humpback, southern right or blue whale on a whale watching tour. The best time to observe these serene mammals is at midday, when the sun is directly overhead.
From September to November, whales and their young can be seen off the coast of Perth on their return journey from the north. Tour operators including Rottnest Express, Rottnest Fast Ferries and Mills Charters offer whale watching tours throughout the season.
Australia's South West
From early June to September see humpback and southern right whales cavorting in Flinders Bay Augusta
as they head for warm waters to mate and breed.
Then from September to December, head to Dunsborough and Busselton to see humpback and rare blue whales and calves take refuge in the calm waters of Geographe Bay.
Albany is a haven for humpback and southern right whales, which mate and calve off the south coast.
From July to October whales can be spotted frolicking and playing in King George Sound, Albany.
This area is famous for its whaling heritage and is not uncommon to see whales playing only a few hundred metres from the station where they once were processed in vast numbers.
The old whaling station has now been transformed into a fascinating interactive whale museum.
Australia's Coral Coast
At Kalbarri, you can witness the migration of humpback whales between June and November. Some of the best vantage points are at Natural Bridge, Eagle Gorge and Red Bluff.
From late March to June each year, experience the once-in-a-lifetime opportunity of snorkelling with the whale sharks at the World Heritage Listed Ningaloo Marine Park.
Australia's North West
If you're headed to the Kimberley region of WA, don't miss the fantastic humpback whale displays. From June to November you can see the humpback whales migrate northwards along the coast to shelter in Camden Sound on the Kimberley coast, as well as Pender Bay and the sheltered waters directly off Broome's coast, where females give birth and suckle their young.
