Two years of failures have left problem-plagued Optus with a multi-million-dollar hit to the brand's crumbling reputation, according to a public relations expert.
Sphere PR Managing Director Louise Roberts said reliability is everything to a telco and, after three triple-zero outages since 2023 and a mass data breach in 2022, Optus' brand has taken repeated blows.
"The Optus brand is now in a fragile, high-risk state," she told 9news.com.au.

"For telcos, reliability and resilience are really non-negotiables, and repeated failures will damage their credibility in ways that a single event may not have."
Roberts said the continued blunders could cost Optus millions in a loss of customers, fines, and a damaged brand reputation.
She added that there may be lawsuits from the families of the three people who died during the triple-zero outage on September 18.
"They'll risk ongoing customer churn, intensified reliability scrutiny, they're probably going to be subject to quite significant fines," Roberts said.
"Companies can recover their reputation, but I think you'll find that Optus' issues will be mentioned for years to come."

Days before the outage, a Roy Morgan survey ranked Optus as Australia's fourth most distrusted brand.
"It still has not recovered from the 2022 data breach," she said.
"Optus has really got to take a long, hard look at itself and make sure that in future, that they have not only invested in their network and resilience, but they have also revised their processes.
"They really need to demonstrate that they've made long-term structural changes."
Optus' problems started years before the first triple-zero outage earlier this month. Here is a breakdown of everything that led to today.
