Thursday Island is one of the town-level numbering areas the ACMA register uses under area code 07 (QLD). The register lists 35 number blocks for it with about 47,000 allocated numbers, held by 18 carriers. A landline that calls you from one of these blocks was issued for the Thursday Island area — though the line may since have been ported, and caller ID can be spoofed.
