Grabbing the chance, Vietnamese officials contacted John Ma'o Kali, who is high commissioner for Papua New Guinea to Australia and asked that the vaccines transfer from PNG to Vietnam.
New Zealand and multilateral institutions will seek and deliver the vaccines back to Papua New Guinea if it needs.
Besides Papua New Guinea in the south Pacific region, Australia is also supporting Vietnam in responding to the pandemic.
Along with its commitment to deliver 1.5 million doses of the AstraZeneca vaccine to Vietnam this year, Australia has also pledged to provide $A40 million to help Vietnam access vaccines over three years.
Of the total, $34 million will be channelled through multilateral mechanisms such as UNICEF to assist with distribution and technical advice and the remaining $6 million will be supported bilaterally.
