The maximum penalty Qantas faces is 10% of annual turnover, which was A$19.8 billion in the year to June, according to Australian consumer laws.
Cass-Gottlieb said the ACCC would seek a fine for Qantas that was "significantly more than" the record A$125 million ($81 million) automaker Volkswagen was fined in 2019 for breaching Australian consumer laws.
"We consider these penalties have been too low, we think the penalty should be in hundreds of millions, not tens of millions", she added.
The regulator has said that Qantas kept selling tickets for an average of 16 days after it had cancelled flights for reasons often within its control.
