Shark comes within metres of swimmers at Mullaloo Beach, WA

Alarming footage has emerged of a large Tiger shark gliding within meters of swimmers at a popular Australian beach.

Two videos filmed on Monday show what appeared to be the same predator in the shallows between Whitfords Beach and Pinaroo Point, just north of Perth, in Western Australia.

In one clip, filmed from the shore, the large shark cruises in waist-deep water with its fin sticking out.

Startled beachgoers can be heard in the video screaming at the sight of it the shark so near to people.

'It's a dolphin,' one surprised girl says. 'It's a Tiger shark,' someone else corrects her. 

Drone footage shows the shark head directly towards a woman before going around her at the last possible moment

But with temperatures hitting the mid-30s, swimmers returned to the water in the afternoon and the shark was back - this time spotted by a drone camera.

At first the animal glides directly towards an oblivious bikini-clad woman, then swims around her at the last possible moment.

It then moves in between her and a nearby father, who unaware, beckons his young son towards him, before turning and heading back to deeper water.

A self-confessed local shark lover, Toby, said in a social media post he went looking for the shark, which he nicknamed 'Trevor'.

He claimed the woman in the clip saw the shark 'did the right thing by calmly getting out', but the father did not.

'Yes the man in the top of the video is signalling his child to join him in the water (he did not see the shark).'

Toby claimed his video, along other videos of 'Trev' in the last months are 'proof that sharks aren't interested in humans'.

'But that being said, accidents do happen so please be SharkSmart and follow the apps for shark movements around Australia,' he added.

The same shark is believed to have forced the closure of Mullaloo on December 15. 

There have been dozens of shark sightings along Perth's coast in the last month.
