Buoyed by her success in Australia, Contos is now taking her campaign global.

“We feel like Canada, UK, Australia are all very aligned on online safety… Then if those three jurisdictions are doing it, it could become a critical mass thing.”

Though experiences like theirs helped inspire these reforms, both Flynn and Varsha are somewhat sceptical of them.

Varsha says she struggles to believe a country like Australia can outmuscle big tech: so she’s not sure the Digital Duty of Care bill will work.
