A woman has claimed a yowie tried to attack her on a country road before she fought it off with a cricket bat.

The terrifying beast was supposedly sighted at about 7pm on March 5 in Nimbin, New South Wales, at the Mr Jerusalem National Park.

Dean Harrison from Australian Yowie Research (AYR) has been studying the mythical creatures for 20 years and claims to have had many encounters with the hairy beasts.

He documents his data in written and audio witness accounts, news articles, images, and physical evidence, the Northern Star reported.

The supposed sighting was recounted on the AYR site and explained how the woman claims she came across the hairy creature.

'It was after cricket training around 6.30pm and I was driving along a dirt road and went over a cow crossing before I pulled over to an area that was bulldozed and the trees were pushed down on the side of the road to do a wee,' the woman wrote.

'I finished my wee when I heard something around me and wasn't sure what it was.'

The woman then decided to howl to see if it was a wild animal hiding behind the trees.

Shocked at getting a response back to her howling, the woman continued to howl until she 'got a growl and a grunting'.

The woman pulled out her cricket back ready to take on whatever was hiding in the bush, thinking it was just some 'smarta** playing a joke on me'.

'It knocked twice, so I knocked back twice. I knocked again, and it did the same back. I thought stuff this and did a howl and a scream - that's when everything went pear shaped.

'I heard thumping coming down the hill...I've never heard anything that heavy before, it was like the ground was moving underneath me.'

Woman's claims: The mysterious creature was suddenly 10 metres away and was growling and grunting as it made its way towards the woman (stock image)

The mysterious creature was suddenly 10 metres away and was growling and grunting as it made its way towards the woman, she claims.

She quickly jumped into her car and turned on the lights and was shocked to see what was standing in front of her.

'It was 6 to 7ft tall and full of hair - about 5 inches long - and it had hair down its cleavage and hair around and on top of its breasts. Its eyes the size of golf balls and its hands were huge reaching the knees.

'It was the scariest thing I've ever seen.'

Flashing the car's headlights on the beast, the woman noticed that it had 'reddish-blue eyes'. It also had a beard and hair over its top lip, she says

'It had a big mouth on it...this mouth was 5 to 7 inches long'.

The creature remained in front of the car swaying side-to-side before it ran away before the woman was able to capture a photo.
