Locals thought it might be Trevor, a tiger shark known by that nickname in local reporting. The footage does not establish that it was the same individual—or that it was harassing swimmers.
Was the shark in the December 2023 footage Trevor?
That remains unconfirmed. PerthNow reported on 7 December 2023 that footage recorded the previous Wednesday showed a tiger shark near swimmers at Mullaloo. The report said some locals believed it was Trevor, a shark previously seen close to shore, but also stated that the identity could not be confirmed. PerthNow’s report described another clip showing the shark in water said to be 25 centimetres deep; that was a descriptive detail in the article, not a scientific measurement.

“Trevor” is a local nickname, not a verified identification. The available reports do not provide a scientific tracking record tying the shark in each clip to one individual. The footage supports saying a tiger shark was filmed near swimmers—not that it deliberately approached or harassed them.
How does the later Mullaloo clip fit in?
A separate video was filmed on New Year’s Eve 2023. PerthNow reported on 2 January 2024 that drone operator Curtis Ramsay filmed a shark, described as about 2.5 metres long, swimming metres from shore. That report connected the sighting with the name Trevor.

Storyful’s metadata for the video, published on 5 January 2024, records Ramsay identifying the shark as Trevor, but explicitly says Storyful had not confirmed it was the same shark. The 2.5-metre description belongs to this later clip; it should not be applied to the Wednesday footage reported in December.
Does this mean Mullaloo Beach is closed now?
No current beach status can be inferred from these archived reports. PerthNow said Mullaloo had not yet been closed that month in December 2023; that is historical information, not a statement about conditions today. Check the SharkSmart alerts and local patrol updates for current sightings, warnings or closures.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What to do if you see a shark or hear an alert
- Check before swimming. Look at SharkSmart and Surf Life Saving WA alerts, and follow local patrol instructions.
- Choose a patrolled beach and swim between the flags. Surf Life Saving WA also advises avoiding dawn and dusk and swimming with others.
- If you see a shark, leave the water quickly and calmly. Report the sighting to Water Police on 08 9442 8600.
- If the warning alarm sounds, leave the water immediately. Follow directions from lifeguards or surf lifesavers on patrol, as Mullaloo Surf Life Saving Club advises.
Surf Life Saving WA’s shark-safety guidance also lists response thresholds: for a shark larger than 3 metres within 1 kilometre, or one 2–3 metres long within 500 metres, it describes a one-kilometre closure either side for one hour, extended at dawn or dusk. For a shark under 2 metres, it says the public is advised while normal operations continue. These are the thresholds stated on that guidance page; check current official alerts and directions for the response to any particular sighting.
