Quick answer
Choose Telstra if coverage is your first priority and you are willing to pay a premium for it. Choose Optus if you want a major carrier, bigger headline data inclusions and more aggressive promotional value in metro or suburban areas.
Coverage and regional differences
This is where Telstra usually earns its premium. Its public SIM-only page continues to anchor the offer around best coverage, while Optus positions itself as a strong major-network alternative with large data and selected-area 5G.
If you spend time in regional or broader travel corridors, Telstra normally deserves the first look. If your life is mostly metro and suburban, Optus can be the more efficient answer.
Data and pricing differences
Optus often looks stronger on data value and promotional pricing. Telstra usually looks stronger on network reach but weaker on cost per included gigabyte.
That means you should compare them as two different products, not just two logos selling interchangeable mobile plans.
Who each carrier suits
Telstra suits coverage-first users, regional households and people who treat reliable reach as non-negotiable. Optus suits shoppers who still want a major carrier but care more about value once their own usage pattern is taken into account.
If you are not sure which category you fall into, start with where you use your phone most rather than the advertised data number.
