0411 filled during the mid-1990s GSM boom as one of the earliest Optus ranges after 0412. Its numbers are old enough that many have cycled through several owners — worth remembering when community reports about a number look contradictory across years.

Worth knowing
- The prefix tells you where a line was issued, not who is calling: range data is not personal data, and the number on your screen can be spoofed.
- Report scam calls to Scamwatch; unwanted telemarketing can be reported to the ACMA once your number has been on the Do Not Call Register for 30 days.
