The public are being asked not to approach whales during their annual migration.
Several whales have been spotted near Perth, off Ocean Reef over the weekend.
Whales often seek out protected waters close to shore and if people harass them they are likely to leave the area.
Whales are not accustomed to people, and may defend themselves when approached.
People who get up close on surfboards and boats are at particular risk, as these whales may react violently, which can result in serious injury or death.
In Western Australia, boats must be within 100m of a whale by law.
You need to keep your distance so they can continue their journey without interference.
People should be able to enjoy the spectacular sight of whales off Perth’s shores for the next few weeks.
If boats and surfers keep their distance, we can all get a view of these creatures from the beach as they pass through our waters.
