The Papua New Guinea cabinet has cleared the way for the finalisation of a sweeping new defence treaty between PNG and Australia.The cabinet’s tick off for the treaty will be a relief to the Australian government after a glitch last month prevented the signing of the treaty when Prime Minister Anthony Albanese was visiting PNG for the celebrations to mark the country’s 50th anniversary of independence.At that time, a quorum of cabinet members could not be gathered to approve the treaty because many had dispersed across the country for the celebrations.
