This study looked at two scenarios: domestically sourced gas from either Queensland’s Bowen and Surat Basins or the Northern Territory’s emerging Beetaloo Basin, transported to southern markets via new and existing pipelines; or internationally sourced LNG through two proposed LNG import facilities at Port Kembla in NSW and Geelong in Victoria. The results showed that gas prices would be higher for both residential and industrial customers in Sydney, Melbourne and Adelaide if they relied on imported LNG rather than domestically sourced gas.
