Kelly Bayer Rosmarin, from lauded executive to public enemy
Kelly Rosmarin, the CEO of Optus, has faced a barrage of criticism and legal action over the past year, following a series of scandals that have tarnished her reputation and the company’s image. Once hailed as one of the top women in Asia Pacific finance and Australian business, Bayer Rosmarin now faces the challenge of restoring trust and confidence in Optus, Australia’s second-largest telecommunications provider.
The network outage debacle
The most recent and damaging blow to Bayer Rosmarin’s leadership came on November 8, 2023, when Optus suffered a massive network outage that affected more than 10 million customers across the country. The outage lasted for more than 12 hours, disrupting phone calls, text messages, internet access, banking services, transport networks, and emergency services. Customers were left frustrated and angry, venting their complaints on social media and demanding compensation.

The cause of the outage was initially unclear, with Optus blaming a “technical network fault” and promising to investigate the issue. However, it later emerged that the outage was triggered by a cyberattack that exploited a vulnerability in Optus’ network equipment, supplied by Chinese vendor Huawei. The attack was allegedly carried out by a hacker group known as “The Dark Army”, which claimed responsibility and demanded a ransom from Optus.
Bayer Rosmarin was widely criticized for her handling of the crisis, as she failed to communicate effectively with customers, regulators, and the media. She did not issue a public apology until the next day and offered only a $100 credit to affected customers, which many considered inadequate and insulting. She also refused to answer questions about the security of Optus’ network and its relationship with Huawei, which has been banned from supplying 5G equipment in Australia due to national security concerns.
The Australian Competition and Consumer Commission (ACCC) launched an investigation into Optus’ conduct, alleging that the company breached its obligations under the Telecommunications Act and the Consumer Law. The ACCC accused Optus of failing to provide reliable and secure services, misleading customers about the cause and extent of the outage, and offering insufficient remedies and compensation. The ACCC is seeking civil penalties, injunctions, and corrective orders from the Federal Court.
The third-party billing scandal
The network outage was not the first time that Optus faced legal action from the ACCC this year. In February 2023, the Federal Court ordered Optus to pay a $10 million penalty for misleading customers over digital purchases, such as games, ringtones, and other content, that were incurred through its third-party billing service.
Optus admitted that it made false or misleading representations in contravention of the ASIC Act, and agreed to apply jointly with the ACCC for orders from the Federal Court. The ACCC alleged that Optus did not properly inform customers that the third-party billing service was a default setting on their accounts and that they would be billed directly by Optus for any content bought through the service, even unintentionally.

Optus also admitted that it knew from at least April 2014 that many customers were being billed for third-party content that they had mistakenly or unknowingly signed up for. The third-party billing service allowed a purchase or subscription to be confirmed and charged to a customer’s bill after just one or two clicks on a web browser. Despite receiving over 600,000 inquiries about the service, Optus failed to put in place appropriate identity verification safeguards and referred customers who sought to query the charges to third parties. Many customers then encountered significant difficulties in canceling the purchases and obtaining refunds from third parties.
The $10 million penalty was one of the highest imposed by the Court after ACCC action on a consumer matter and equaled the penalty paid by Telstra in 2022 after it admitted to similar conduct with its Premium Direct Billing service. The ACCC said that Optus’ conduct was “simply unacceptable” and deserved a significant penalty.
About 240,000 Optus customers have so far been refunded. The ACCC understands Optus has paid about $8 million in refunds and third-party providers another $13 million. Optus has committed to contacting potentially impacted customers who complained about the services and have not already received a refund, as well as those customers whom Optus identifies as having been incorrectly charged.
The NBN speed claims case
Another legal dispute that Optus faced this year involved its claims about the speed and performance of its NBN plans. In June 2023, the ACCC sued Optus for allegedly misleading customers about the need to move to the NBN.
The ACCC alleged that Optus sent emails to about 138,000 of its mobile customers, telling them that their existing broadband service would be “disconnected very soon” and that they had to move to the NBN if they wanted to keep using Optus services. The ACCC claimed that these statements were false or misleading, as Optus had no reasonable basis to believe that the customers’ existing services would be disconnected in the near future and that the customers could choose to keep their current service or switch to any NBN provider, not just Optus.
The ACCC also alleged that Optus created a false sense of urgency by telling customers that they had as little as 30 days to move to the NBN, when in fact they had much longer. The ACCC said that Optus’ conduct was “unacceptable” and “exploited” customers’ confusion about the NBN migration process.
Optus admitted to the ACCC’s allegations and agreed to pay a $6.4 million penalty, subject to the Court’s approval. Optus also apologized to the affected customers and offered them the option to cancel their NBN contract without penalty. Optus said that it had made an error and that it had cooperated with the ACCC’s investigation.
The impact on Optus and Bayer Rosmarin
The legal disputes that Optus has faced this year have had a significant impact on the company’s reputation, customer satisfaction, and financial performance. Optus has lost market share and revenue to its competitors, especially Telstra, which has capitalized on Optus’ woes by offering superior network coverage, reliability, and security.
Optus has also faced increased scrutiny and pressure from regulators, politicians, and the public, who have questioned its ability to provide quality and affordable services to Australians.
