Starting October 1, Australia's three major telecom companies—Telstra, Optus, and TPG—will activate temporary disaster roaming (TDR) in regional areas where severe weather disrupts mobile service. This initiative allows customers to use a rival network for basic communication services when their own network goes down. However, it will not be effective in vast parts of regional Australia that have only one provider. While the telecommunications industry and government have tested TDR extensively, no specific accountability measures or success criteria have been established beyond monitoring by the companies themselves.

using this article's own text rather than the other coverage of the
same event (that is the story summary below).
In short:
From October 1, telcos will activate temporary disaster roaming (TDR) when one network goes down during a severe weather event.
asserted
network → activate → event
It will only be available in areas outside major cities where there is an alternative network, meaning it won't work in large parts of regional Australia serviced by one provider.
asserted
it → be → provider
The telcos will decide when to switch roaming on and off, but neither the industry nor government has outlined accountability measures.
asserted
industry → decide → measures
After years of testing, Australia's three major telcos are ready to switch on a system that would give customers access to a rival network if their own goes down during a weather emergency.
asserted
own → switch → emergency
Known as temporary disaster roaming (TDR), Telstra, Optus and TPG will work together to decide when to activate it in regional areas where a mobile service has been disrupted by severe weather.
"You'll continue to be able to make phone calls, send text messages, and you'll have limited capacity data services," the chief executive of Australian Telecommunications Alliance, Luke Coleman, said.
asserted
executive → know → Alliance
"You can't expect to have your full usual high-speed data, but you will still have enough data to send a WhatsApp or an iMessage, maybe even to check an emergency service website like Fires Near Me, for example."
asserted
you → expect → example
For TDR to work, there must be another network available in that area that mobile users can roam onto.
asserted
users → work → that
That means it will not work in large parts of regional Australia, which are only serviced by one provider.
asserted
which → mean → provider
Regional Independent MP Helen Haines has long been advocating for such a service, which she described as a "game changer".
asserted
she → advocate → changer
"When disaster knocks in regional communities and pulls out a mobile network, people shouldn't have to wait for their own provider to restore that service before they can reconnect," she said.
asserted
she → knock → service
"This is existential in times of disaster."
Telcos in charge
TDR is already available in some form, either mandated or agreed to by industry, in several countries including the United States and Japan.
asserted
TDR → mandate → States
In 2023, the Australian Competition and Consumer Commission found that TDR was technically feasible, and in 2024 the Regional Telecommunications Review recommended that it be mandated "at the earliest possible opportunity".
asserted
it → find → opportunity
It was something Ms Haines previously tried to have legislated with a private members' bill and amendments, but it did not have the support of the government.
asserted
it → try → government
"I'll keep pushing to make sure that the telecommunications companies ensure that there's enough network capacity to facilitate temporary disaster roaming, that the telecommunication companies ensure that there's power backup to our mobile network," she said.
asserted
she → keep → network
Mr Coleman said the telcos were best placed to be the custodians of the initiative as they "have full visibility of the network's capacity" and could make sure the "surviving network continues to operate".
uncertain
network → say → capacity
He said telcos would monitor its progress but did not specify any benchmarks or framework to measure success.
"The telcos are being good corporate citizens here and this is part of rebuilding trust with Australians to show that there is no additional charge for this,"Mr Coleman said.
asserted
Coleman → say → Australians
"If you're a consumer, your phone will just automatically start using another available network where it is safe to do so.
asserted
it → start → network
"
Under the terms of the agreement, the service will only be made available outside of major cities and will only be implemented in up to three different disaster areas at any one time.
asserted
service → make → time
When asked how a decision would be made in a situation where multiple areas in the same region might be affected, Mr Coleman said telcos were best placed to make a choice.
uncertain
telcos → ask → choice
"Those areas do need to be spaced a certain distance apart because there is a risk otherwise of the network being overloaded," he said.
asserted
he → need → ?
A statement quoting a ministerial spokesperson did not answer questions posed by the ABC, including whether there would be any accountability around the initiative.
asserted
statement → quote → initiative
"The government will continue to engage closely with industry to make sure TDR is working as intended to keep communities safer," the statement said.
asserted
statement → continue → communities
No change to Triple Zero
Mobile roaming is different to an existing permanent provision known as "camp on" that allows mobile users to call Triple Zero (000) no matter what network they are subscribed to, as long as there is at least one network available.
asserted
they → exist → network
For TDR, Mr Coleman said "most modern smartphones" would have settings to enable VoLTE technology, which would allow them to roam when activated.
asserted
them → say → technology
He would not confirm if there would be subsidies for anyone needing to upgrade their phone, but encouraged people to approach their telco for advice.
asserted
He → confirm → advice
TDR is also different from domestic roaming, which the ACCC is currently reviewing to see if it should be mandated on a permanent and more widespread basis.
asserted
it → review → basis
