PET owners are also being warned of the dangers of heatstroke this summer, particularly in dogs.
Despite the recent wet weather, temperatures are still warm enough to affect pets.
According to Murdoch University's Veterinary Hospital director Mark Lawrie, heatstroke is one of the most dangerous yet easily prevented conditions affecting dogs.
"Dogs are so eager to please their owners - they often won't stop playing until their bodies can't take any more," Dr Lawrie said.
"Owners need to watch for warning signs of heatstroke, such as heavy panting, and act quickly.
"Days with temperatures of over 30 degrees bring an increased risk of heatstroke - and days of 36C or more make it a lot harder for your dog to cool down."
Particularly dangerous situations for all dogs include driving in cars if the dog's area of the car is not air-conditioned or cross-ventilated, and exercising in the heat of the day.
"And, of course, dogs must not be left in cars, even with the windows down. They can die very quickly," Dr Lawrie said.
