Australians caught out in the massive Optus data breach may be able to change their driver's licence numbers.
At a Labor caucus meeting on Tuesday, Attorney-General Mark Dreyfus was asked about the trove of information stolen, and said the option was being considered with the privacy commissioner.
He said the commissioner wasn't notified by Optus of the breach involving almost 10 million customers, until late Friday, the day after it was first reported.
