The woman continued despite her interjection, saying: "Your kids behead people in Syria. [...] Read the newspapers, 148 people, Christians murdered in Kenya. They're killing each other in Syria."
Ms Eden interrupted again at this point, telling her angrily: "Don't sit there disrespecting someone that has nothing to do with it. Have some respect. If you've got nothing nice to say, don't say anything."
The footage immediately attracted hundreds of likes, shares and comments praising her for stepping in and defending the Muslim woman against harassment.
Mariam Veiszadeh, of the Islamophobia Register Australia, told the Sydney Morning Herald she was heartened by Ms Eden's stand. "We hope that her actions inspire others to stand up against racial or religious vilification," she said.
"We're not in the midst of an imaginary backlash, Islamophobia is very much real and you can see from the video it has devastating consequences for Muslim women."
Ms Eden said she was "overwhelmed" by the positive response to the video. "I didn't realise how something so small would end up becoming so important," she wrote on her Facebook page.
"I genuinely have tears in my eyes at the messages people have sent me."
