Australia and Papua New Guinea are set to strengthen security ties on the first day of Prime Minister Anthony Albanese's trip to the region.

Mr Albanese became the first foreign leader to address PNG's parliament, pledging a new defence pact with Australia's northern neighbour.

"Australia and Papua New Guinea have a chance to deepen our defence ties by enhancing our national security co-operation and achieving a swift conclusion to negotiations on a bilateral security treaty," he said.

"A treaty that will underpin our work together to address PNG's priority needs including law and order challenges, strengthening the justice system and rule of law and a treaty that builds on the family-first approach to regional security."

Australia, the United States and other allies have been seeking a deal after China signed a security pact with the Solomon Islands.

"This can be a decisive decade for peace, prosperity, unity and security in the Indo-Pacific," Mr Albanese said.

Mr Albanese received a ceremonial welcome as he touched down in Port Moresby on Thursday morning, becoming the first Australian leader to visit the country since 2018.

He was greeted by PNG's deputy prime minister John Rosso on arrival, as well as foreign minister Justin Tkatchenko and Australian high commissioner Jon Philp.

Mr Albanese will give his PNG counterpart James Marape an Akubra Cattleman hat made in Kempsey when they hold bilateral talks later in the day.

Mr Tkatchenko said in an earlier interview the security treaty would enhance the capabilities of the PNG defence force.

"It's all about making sure that our defence force and its infrastructure and its capabilities are able to meet modern-day standards and the situations that we face now in the region," he told the ABC.

Pacific Minister Pat Conroy said the details of the treaty would ultimately set up the legal framework for greater security cooperation.

"That could include, hypothetically, allowing more visits by Australian naval vessels or Papua New Guinea naval vessels to Australia, it could include greater military cooperation in training," he said.

PNG soldiers supported Australian communities during the bushfire crisis in 2020.

Mr Albanese said the two nations had a leadership role on climate change in the Pacific.

"There is not a moment to waste. It is up to our generation to protect the precious and unique natural environment of our rainforests, reefs and coasts," he said.

"To build - and plan - our infrastructure so our communities are more resilient and better prepared for natural disasters."

He also urged the region to continue pushing into clean energy technology and "grasp the transformative economic benefits".

Australia and Papua New Guinea have committed to a new security deal which is set to be signed in June.

Leaders Anthony Albanese and James Marape agreed to a joint statement of commitment to a security treaty between the two countries at a meeting in Port Moresby on Thursday.

In the joint statement, the respective prime ministers said the deal would "reflect the evolving nature of our shared security interests, recognising that non-traditional security challenges, such as climate change, cyber security, and economic elements of statecraft, affect our strategic environment".

Foreign ministers have been asked to conclude negotiations by the end of April so the leaders can sign it in June.

Earlier in the day, Mr Albanese became the first foreign leader to address PNG's parliament, pledging the new defence pact with Australia's northern neighbour.

"Australia and Papua New Guinea have a chance to deepen our defence ties by enhancing our national security co-operation and achieving a swift conclusion to negotiations on a bilateral security treaty," he said.

"A treaty that will underpin our work together to address PNG's priority needs including law and order challenges, strengthening the justice system and rule of law and a treaty that builds on the family-first approach to regional security."

Australia, the United States and other allies have been seeking a deal after China signed a security pact with the Solomon Islands.

"This can be a decisive decade for peace, prosperity, unity and security in the Indo-Pacific," Mr Albanese said.

Mr Albanese received a ceremonial welcome as he touched down in Port Moresby, becoming the first Australian leader to visit the country since 2018.

He later gave Mr Marape an Akubra Cattleman hat made in Kempsey during talks.

"We are elevating to higher heights how we relate," Mr Marape said.

PNG officials said the defence deal was about ensuring the country's military met "modern-day standards".

Pacific Minister Pat Conroy said the details of the treaty would ultimately set up the legal framework for greater security co-operation.

"That could include, hypothetically, allowing more visits by Australian naval vessels or Papua New Guinea naval vessels to Australia, it could include greater military co-operation in training," he said.

Australia and Papua New Guinea are set to sign a document to progress a defence treaty on the first day of Prime Minister Anthony Albanese's trip to the region.

Papua New Guinea's minister for foreign affairs Justin Tkatchenko confirmed the two countries would sign off on a key document that would take the sought-after deal to the next level on Thursday.

"We are very close and today will be a historical day between Papua New Guinea and Australia, where we will actually sign off and agree to the Security Treaty after many years, and it will be the pinnacle of the visit for the next two days of the Australian prime minister, it'll be signed today," Mr Tkatchenko told ABC Radio National.

He said the deal would enhance the capabilities of the PNG defence force.

"It's all about enhancing PNGs capabilities and making sure that our defence force and its infrastructure and its capabilities are able to meet modern-day standards and the situations that we face now in the region."

Anthony Albanese will become the first foreign leader to speak at the PNG parliament on Thursday.

The wide-ranging speech will touch on climate change, education, health, biosecurity and infrastructure, but it's Mr Albanese's defence comments that will stand out, with fears of China's growing influence in the region.

"Australia and Papua New Guinea have a chance to ... deepen our defence ties (by) enhancing our national security co-operation and achieving a swift conclusion to negotiations on a bilateral security treaty," he will say in his speech on Thursday.

"A treaty that will underpin our work together to address PNG's priority needs including law and order challenges, strengthening the justice system and rule of law ... and a treaty that builds on the family-first approach to regional security."

Australia, the United States and other allies have been seeking a deal after China signed a security pact with the Solomon Islands last year.

"This can be a decisive decade for peace, prosperity, unity and security in the Indo-Pacific," Mr Albanese will say.

Minister for International Development and the Pacific, Pat Conroy, said the details of the treaty would ultimately set up the legal framework for greater security cooperation.

"That could include, hypothetically, allowing more visits by Australian naval vessels or Papua New Guinea naval vessels to Australia, it could include greater military cooperation in training," he told ABC radio.

Mr Conroy, who will travel with the prime minister to PNG, said the visit would strengthen ties between the two nations in areas other than defence.

"It's about making it easier for Australia to support the security aspirations of Papua New Guinea and vice versa, noting that PNG soldiers supported us during the bushfire crisis of a few years ago," he told ABC radio.

Climate change will also feature prominently, with the prime minister calling for the two nations to "show leadership and take action" in the Pacific.

"There is not a moment to waste. It is up to our generation to protect the precious and unique natural environment of our rainforests, reefs and coasts," he will say.

"To build - and plan - our infrastructure so our communities are more resilient and better prepared for natural disasters."

He will also urge the region to continue pushing into clean energy technology and "grasp the transformative economic benefits".

Anthony Albanese will use his historic address to Papua New Guinea's parliament to call for a "swift conclusion" of security pact negotiations between the nations.

In becoming the first foreign leader to speak at the PNG parliament, the prime minister will call his hosts "neighbours who stand with each other and help each other in times of need" and ask a highly sought-after deal be finalised.

The wide-ranging speech will touch on climate change, education, health, biosecurity and infrastructure, but it's Mr Albanese's defence comments that will stand out, with fears of China's growing influence in the region.

"Australia and Papua New Guinea have a chance to ... deepen our defence ties (by) enhancing our national security co-operation and achieving a swift conclusion to negotiations on a bilateral security treaty," he will say in his speech on Thursday.

Australia, the United States and other allies have been seeking a deal after China signed a security pact with the Solomon Islands last year.

"This can be a decisive decade for peace, prosperity, unity and security in the Indo-Pacific," Mr Albanese will say.

Minister for international development and the Pacific, Pat Conroy, said the details of the treaty were still being negotiated but it would ultimately set up the legal framework for greater security cooperation.

"That could include, hypothetically, allowing more visits by Australian naval vessels or Papua New Guinea naval vessels to Australia, it could include greater military cooperation in training," he told ABC radio.

Mr Conroy, who will travel with the prime minister to PNG, said the visit would strengthen ties between the two nations in areas other than defence.
