Updated Telstra's mobile network experienced a nationwide outage on Monday morning, May 21st, 2018.
For a while, according to some media reports, the carrier's outage reporter was also down, but at the time of writing it was working well enough to identify local outages, report that the cause is under investigation, and advise that services will return at a “time to be confirmed”.

Telstra acknowledged the outage on Twitter at 10:55am Monday:
We’re working to fix an issue impacting some mobile services. Sorry for the inconvenience.— Telstra (@Telstra) May 21, 2018
The outage is stopping people contacting emergency services via Telstra:
This outage may affect those attempting to call Triple Zero - 000 or Police Assistance Line - 131 444.— NSW Police (@nswpolice) May 21, 2018
Until issue is resolved, police are advising those affected, where possible, to use a phone belonging to another carrier or a landline when attempting to call these numbers. https://t.co/9uiBfnY4ek
Because some rail networks depend on Telstra for communications, there were also flow-on effects to their operations. For example, Victoria's V-Line had a cancellation:
12:10 Southern Cross - Waurn Ponds train will not run due to a Telstra outage. Customers are asked to travel per the 12:30 SCS to South Geelong.— V/Line Geelong Line (@vline_geelong) May 21, 2018
Some Twitter users reported having their access limited to 3G.
At the time of writing, this Telstra-using author had sporadic access to voice calls, but no data access. Other Vulture South Operatives have had cals to Telstra users go to voicemail, but TXT messages make it through.
Update: Services began returning around midday. ®
