Australia's second-largest telecommunications company has agreed to pay a record fine for its "unconscionable conduct" in targeting disadvantaged and Indigenous customers.

Optus has agreed to a $100 million penalty after targeting intellectually disabled customers and Aboriginal people living in remote communities that weren't covered by its mobile network.
