Optus has apologised to people affected by last week's cyber attack, admitting that it needs to communicate better with people caught up in the data breach.
The telecommunications company took out full-page advertisements in major newspapers around the country to say how "deeply sorry" it was.
"We've heard your message that we need to communicate more clearly," the ad says.
"That's why we've now put together easily accessible materials for you to stay informed on the actions you can take."
It directs people to a website dedicated to updates about the cyber attack.
What does the ad say?

What's the latest update?
As of Saturday morning, the Optus website's latest update was about Friday's press conference from the Australia Federal Police (AFP) about Operation Guardian.
It says the AFP would "supercharge" the protection of more than 10,000 customers whose details were published online on Tuesday.
An online account that claimed to be behind the attack asked for a ransom of $US1 million and threatened to release customers' details if it wasn't paid.
On Tuesday morning, the account released the details of more than 10,000 people on an online forum before deleting the post and apologising a few hours later.
"Customers affected by the breach will receive multi-jurisdictional and multi-layered protection from identity crime and financial fraud," Optus' website says.
"The 10,000 individuals, who potentially had 100 points of identification released online, will be prioritised."
