Koumala: landline numbers and carriers
Koumala is one of the town-level numbering areas the ACMA register uses under area code 07 (QLD). The register lists 31 number blocks for it with about 13,100 allocated numbers, held by 18 carriers. A landline that calls you from one of these blocks was issued for the Koumala area — though the line may since have been ported, and caller ID can be spoofed.
