A mother filmed the tense moment she confronted a stranger for making an inappropriate comment to her young daughter.
The teenage girl was buying lunch at Routley's Bakery in the beachside town of Torquay, south-west of Melbourne, on Saturday.
Another customer suggested her order would go straight to her hips.
The teenager told her mother, who went on to confront the man outside the bakery.
'Is there a problem?' she asked.
'No,' the man replied.
The woman continued: 'No? So you're not going to make any more comments about young girls' bodies while they're in a shop buying food?'
The man denied the comment was about the girl's body, prompting the mother to repeatedly ask what he said.
An Aussie mother has been inundated with support after she confronted a man who made an offensive comment to her teenage daughter
'I said, "It'll go straight to your hips",' the man replied, while trying to shield his face.
'I wasn't talking about her body.'
The mother disagreed and accused the man of body shaming.
'You're in a public place and you're making comments to strangers,' she added.
The man accused the woman of not having a sense of humour, but then admitted he has no daughters.
'Well, I'm glad that you don't, because it's actually a revolting comment to make to a young girl,' the woman told him.
The man apologised for the comment but then accused the woman of being overprotective, sparking an angry reaction.
'You should be sorry and learn that when you're out in public and someone's buying food, you need not make a comment about young people's bodies,' she continued.

The next day, the mother shared a follow-up post to thank everyone for the overwhelming support and messages.
'I didn't expect my video to reach as far as it did but I'm genuinely overwhelmed by the support, kindness and messages of encouragement,' she wrote.
'Thank you for backing us and creating a space where this behaviour is called out and not ignored.'
She added that her daughter was doing 'just fine' as she doubled down on the confrontation.
'She is surrounded by love and protection and is a strong young woman,' the mother continued.
'While she is still maturing, she is already a fierce and courageous young human.
'And let me be very clear - I will always protect her loudly and unapologetically from anyone who even thinks about crossing that line.'
Daily Mail contacted the mother for comment.
