'Snitching on your neighbour': Controversial commentator sparks debate after calling out 'un-Australian' person for dobbing on Sydney family who left lockdown to go to a pony club

A right-wing commentator has sparked debate by labelling a vigilante who tipped off the police about a family breaching coronavirus restrictions as 'un-Australian'.

The family from Sydney's eastern suburbs disobeyed stay-at-home orders to attend a pony club event 270km away in the NSW Hunter Valley, where they were busted by police not wearing masks.

Controversial Melbourne commentator Avi Yemini weighed into the debate to slam the horse trial event attendee who 'snitched' on the family of three.

'NSW Police stopped and fined a Sydney family following a Crime Stoppers tip-off by a member of the public that they were attending a pony club in Hunter Valley,' he tweeted.

'Snitching on your neighbour is the most un-Australian act possible. SHAME ON YOU.'

Yemini's tweet divided public opinion, with many agreeing dobbing in fellow Australians was unacceptable, but others thought Covid was too important.

'People should be ashamed of themselves, living in fear daily. Grow a pair and stop thinking the government cares about you,' one agreed. 

But another disagreed: 'How is driving three hours and 200km to ride your horse acceptable?'

Another added: 'Just for a moment I thought Avi was going to be balanced and have a crack at NSW Police for arresting lockdown breakers. But no, he found a way to avoid doing so.'

NSW Police have issued dozens of penalty infringement notices since restrictions were enforced on Friday. Pictured are officers patrolling the streets in Parramatta

A Paddington man, 56 and Maroubra woman, 22, were each fined $1,000 for travelling from Sydney and were slugged another $200 each for not wearing a mask.

A teenage girl, 13, was issued a warning.

The incident in the small Hunter Valley town of Denman sparked community concern.

'The guidelines were a bit fuzzy to begin with, it's just disappointing that they've come to our little town,' Denman Pony Club secretary Jayne Parker told the ABC.

'I hope that we can continue to run our regional events and maybe be a little more diligent with who comes in and who goes out.'

NSW Police repeated its appeal to the community to report suspected breaches of the public health orders that are in place until at least July 9.

Sydneysiders can only to leave their homes for four reasons, including work, shopping for essential items, seeking medical care, or for caregiving or compassionate reasons.

The same restrictions extend to the surrounding Blue Mountains, Wollongong, and Central Coast regions as NSW recorded 30 new locally-acquired cases on Sunday.

'No matter how people think that they have to attend some of these events with their children or need to go on holidays, public health orders are clear,' NSW Police Deputy Commissioner Gary Worboys said.

'The family were issued an infringement notice and that will happen to any family who has travelled outside the metropolitan area and against public health orders.' 

Mr Yemini is a former Israeli soldier who ran a gym in Melbourne before moving on to run communications for fellow far-right activist Tommy Robinson in Britain.

He has since returned to Australia and fashioned himself as a political commentator on YouTube and for Rebel News and other fringe outlets.
