Tilley Swamp: landline numbers and carriers

The register lists 30 number blocks for it with about 33,000 allocated numbers, held by 20 carriers. A landline that calls you from one of these blocks was issued for the Tilley Swamp area — though the line may since have been ported, and caller ID can be spoofed.
