Surfer Sean Pollard was mauled by a shark at Wylie Bay near Esperance in 2014. The two beaches are less than 8km apart. He lost his right hand and his left arm above the elbow.
He later shared his story with 60 Minutes, recounting the attack in detail.
In June last year, Doreen Collyer, 60, died after being attacked by a large great white shark while diving one kilometre off the Perth coast.
Fishermen who arrived at the scene to render assistance said they spotted the shark and claimed it was larger than their 5.3m boat.
One month earlier, Ben Gerring, 29, died after having his leg severed by a great white shark at Falcon Beach.
The Shark Smart WA website lists two shark sightings in an area to the west of Esperance over the past week: a medium-sized great white 150m off shore last Tuesday at Two Mile Beach in Hopetoun, and the same shark also seen 300m off shore at Crazies Reef.
