"During the Optus outage in 2023, Australians joked about not being able to buy a coffee, pay for lunch or order an Uber," the article observed — and then argued that the joke missed the point.
During the Optus outage in 2023: a narrow lesson, a broader wake-up call
The Optus outage became shorthand for payments being interrupted. The piece argues that was the wrong takeaway: the disruption exposed how deeply Australia’s economy now depends on digital systems that enable the full process of economic exchange, not only the transfer of money. Payment, the article stresses, is only one step in a larger sequence through which households, businesses and governments obtain and provide goods and services.
Economic exchange: ordering, identity, delivery and settlement
To illustrate the distinction, the article lists concrete examples beyond point-of-sale payments: a farmer ordering fertiliser, a supermarket replenishing its shelves, a hospital receiving medicines, and a freight company accepting a delivery contract. Those exchanges require more than bank rails. Buyers and sellers must communicate, place orders, verify identities, move goods and settle accounts. Any link in that chain can fail even when payment systems themselves remain operational.

End the scrambleShared dependencies: telecommunications, cloud services, digital identity and payment platforms
The article highlights that every critical sector — food, healthcare, mining, manufacturing, retail — relies on a set of common enabling systems. Telecommunications outages can simultaneously interrupt communications, authentication and digital payments; cloud providers underpin ordering and logistics; digital identity services support verification across sectors. The danger is not a single point failure, the piece warns, but concurrent or cascading failures across these concentrated dependencies.
Current resilience work, and where responsibility is fragmented
The article is careful to note that Australia has not ignored cybersecurity or payment resilience. "Governments, regulators and industry have invested heavily in both," it says, and financial services are recognised as critical infrastructure. It also reports that "the Reserve Bank is focusing on the resilience of Australia’s payment systems." Yet the author argues much resilience planning remains organised by sector, with separate arrangements for telecommunications, banking, transport, energy and food. That siloed approach, the piece contends, leaves responsibility for understanding cross-sector interactions fragmented across institutions and policy portfolios.
International precedents: Sweden, the Netherlands and Taiwan
The article points to concrete overseas examples that test or plan for multi-domain disruption. Sweden has developed offline payment arrangements for essential retail purchases during crises. The Netherlands encourages preparation for prolonged electronic-payment disruption. Taiwan runs a whole-of-society resilience program that tests how governments, businesses and communities continue functioning during complex emergencies. The author does not advocate copying any single model, but says these cases demonstrate the value of testing essential national functions rather than individual systems.
Who should join a national desktop exercise — telecommunications providers, banks, supermarkets, fuel distributors, freight operators, healthcare providers, agricultural producers, cloud providers, regulators and emergency-management agencies
- Telecommunications providers: the article identifies comms as a common failure point that can interrupt ordering, authentication and payments simultaneously.
- Banks and payment providers: noted as having redundancy and contingency arrangements, they are central but insufficient on their own to preserve economic exchange.
- Supermarkets, fuel distributors, freight operators and agricultural producers: named as participants whose operational exchanges (stocking, fuel supply, freight contracts, inputs like fertiliser) depend on shared digital services.
- Cloud providers, regulators and emergency-management agencies: included to surface shared dependencies, map cascading failures and design degraded-mode operations for essential exchanges.
The article proposes a "national desktop exercise focused on maintaining economic exchange during prolonged, cross-sector disruption." The objective would be to identify which exchanges are essential, where shared dependencies exist, how failures cascade and how essential services could continue under degraded conditions — not merely to restore payments.
It also notes practical mitigations already in place: banks maintain redundancy, payment providers have contingency arrangements and cash remains an important fallback. Those buffers are real, the author concedes, but they are no panacea against concentrated digital dependencies that span multiple sectors at once.
Conclusion: the next test, the piece argues, should be systemic rather than sectoral. Instead of another sector strategy, the article says the logical next step is an exercise and planning effort that treats economic exchange itself as the essential national function to be preserved: ensuring Australia can continue obtaining and providing what society needs when the digital systems underpinning economic life come under pressure.
