The Do Not Call Register is a free service that allows people register their home, personal mobile or fax number to reduce telemarketing calls.
Once your numbers are listed on the register, telemarketers and fax marketers must not contact you.
Some groups can still contact you after you register. These include charities, research companies, political parties and educational institutions.
You can sign up online at https://www.donotcall.gov.au or by calling 1300 792 958.
