Prime Minister Anthony Albanese has committed to working with Japan and the United States to shore up peace and stability in the Indo-Pacific region.

Mr Albanese met with his Japanese counterpart Fumio Kishida and US vice president Kamala Harris in Tokyo on Tuesday ahead of attending the state funeral for Shinzo Abe.

Mr Abe was integral to establishing the Quad security dialogue, involving Australia, the US, Japan and India.

Speaking at the start of a bilateral meeting with Mr Kishida, Mr Albanese said the two nations were working towards a free and open Indo-Pacific.

"(It) is so important we continue to work together and to work with our partners as well to advance the common interest," he said.

Mr Albanese offered his condolences for the death of Mr Abe, saying there was a high-level attendance from Australia "to pay our respects ...to not just his family but to the people of Japan".

At the meeting with the vice president, Mr Albanese thanked the US for its interest in, and support for, the region.

"We live in uncertain times, there is strategic competition. It is something we are very conscious of in the Pacific," he said.

Ms Harris pledged to work towards the "combined goal of peace and security in the Indo-Pacific".

She also lauded Australia's new emissions reduction target, saying Mr Albanese "received admiration" for his climate goals.

The US recently passed the Inflation Reduction Act, providing hundreds of billions of dollars for climate action.

"We believe the combination of the two will accelerate the work our two nations can do," she told the prime minister.

With Mr Albanese in Tokyo were former prime ministers John Howard, Tony Abbott and Malcolm Turnbull, who wanted to pay tribute to Mr Abe, who was assassinated in July.

Papua New Guinea Prime Minister James Marape also travelled with Mr Albanese.

"We are here to celebrate the life of Shinzo Abe. The tragic circumstances of this assassination is something which reverberated around the world," Mr Albanese said.

"I'm here with three former prime ministers. What that says is how important the relationship between Australia and Japan is but it also says how important the respect is and the standing Shinzo Abe had."

Mr Abe was Japan's longest-serving prime minister, from 2006 to 2007 and 2012 to 2020.

The ceremony at Nippon Budokan Hall in central Tokyo - attended by more than 4300 foreign dignitaries and other guests - began with his widow Akie carrying in an urn containing his ashes.

A moment of silence was followed by a retrospective of Mr Abe's political life and a 19-gun salute.

Protesters gathered in Tokyo to express their anger at the $17.7 million cost of the state funeral - the first such event since 1967.

Melissa Caddick's husband denies ever lying about his wife's disappearance to police, however admits he misdescribed events because he was confused.

At the NSW Coroners Court on Tuesday, Anthony Koletti told the inquest into his wife's disappearance and suspected death that during the day before she went missing, he was so concerned about her welfare that he "didn't want to leave her alone".

However, in an interview with police 11 days after Mr Koletti reported her missing, he described her demeanour on the night of the ASIC search over her alleged fraud as "very loving and very normal".

Counsel assisting Jason Downing SC asked Mr Koletti if he was "too confused or emotional to give an accurate description her behaviour".

"Yes," Mr Koletti responded, "I wouldn't say I wasn't confused."

The court was also shown a segment of 7News' Spotlight, where Mr Koletti recounted the raid as "inhumane", saying he and Ms Caddick were offered no food, water, medical or psychological attention.

Mr Koletti was asked if he meant that no one offered her medical attention throughout the day.

"That's right," he said, "I didn't believe anyone there could offer it so I offered it myself."

He maintains he had no inkling his wife was defrauding family and friends of millions of dollars, nor did he ask her why federal police or the corporate watchdog was suddenly raiding their Sydney eastern suburbs home.

"Does the truthful answer depend on who is asking it and why?" Mr Downing said.

"No," Mr Koletti said

Following the 12-hour search by the Australian Federal Police and the Australian Securities and Investments Commission, Mr Koletti said he didn't ask Ms Caddick what was happening and they just went to bed.

"Are there many truths?" Mr Downing said.

"There is one truth," Mr Koletti said.

Mr Koletti said he has always been truthful but admitted there may have been moments when his "wires were crossed" due to his concern and worry.

Throughout the day he observed his wife "a little bit shaky," and said she seemed distant and vague, so he offered to make her a coffee.

Mr Downing asked at any point did he ask why ASIC was extensively searching through his wife's business office, and seizing hardware and valuable items.

"No I don't believe I was really worried about that, at that point in time. I was just under the belief that she had done nothing wrong."

Mr Koletti agreed the event was abnormal and quite shocking.

"It was certainly a surprise to me," Mr Koletti said.

Mr Koletti reported the 49-year-old as missing some 30 hours after he says she walked out of their home for the last time on November 12, 2020 about 5.30am to go for a walk.

His stories to police about the last time he saw his wife have been inconsistent and subject to intense scrutiny during the inquest.

Earlier on Tuesday the inquest heard from Dominique Ogilvie, one of the few investors to recoup her investment of $2.5 million plus a purported $380,000 in profit from Ms Caddick when she was alerted to some of her illegal behaviour.

Ms Ogilvie had met the conwoman while holidaying in Aspen, Colorado, staying in an apartment Ms Caddick claimed to own.

On September 14 Ms Ogilvie was formally interviewed by ASIC, but still wasn't quite sure of the size of the fraud, she said.

She denied ever having told Ms Caddick about the ASIC investigation.

In February 2021 Ms Caddick's decomposing foot encased in an Asics shoe washed ashore at Bournda Beach on the NSW south coast, about 400km south of Sydney.

The inquest continues.

Melissa Caddick's husband denies ever lying about his wife's disappearance but agreed at her inquest that his inconsistent statements were inaccurate and that he has misdescribed events.

Anthony Koletti in the NSW Coroners Court was taken to police statements, interviews, court documents and a $150,000 paid spot on 7News' Spotlight program.

It details the moments after the last verified sighting of Ms Caddick during a 12-hour search by the Australian Federal Police and the corporate watchdog on November 11, 2020.

The hairdresser and part-time DJ told a journalist he stayed up until 4am that night writing music, but on Tuesday he gave evidence that he had gone to bed with his wife before later getting up due to his sleep apnoea.

Counsel assisting Jason Downing SC said Mr Koletti was not giving honest answers and trying to "scramble, explain his answers" to make them "gel" in court.

"That's not correct, you are saying it in a way that's confusing me," Mr Koletti said.

The court was also shown the news interview where Mr Koletti recounted the raid as "inhumane", saying he and Ms Caddick were offered no food, water, medical or psychological attention.

Mr Koletti was asked if he meant that no one offered her medical attention throughout the day.

"That's right," he said, "I didn't believe anyone there could offer it so I offered it myself."

He was later asked if so concerned why not book a medical specialist himself.

"All I could do was comfort her in the few hours I had left with her," Mr Koletti said.

Mr Downing said the details were "not minor" and in connection with Ms Caddick's disappearance.

"You put down misdescribing everything that night because you were shaken and distraught," Mr Downing said.

"I would say it's not an accurate description," Mr Koletti said.

He was also referred to previous police reports that he assumed she had gone out jogging because that was her daily routine.

On Tuesday he said she "had no habits" and that she "used to do this, used to do that," including walking with friends outside or jogging inside on the treadmill.

A subsequent review of video records revealed Ms Caddick had not been jogging for weeks before she disappeared.

Mr Koletti maintains he had no inkling his wife was defrauding family and friends of millions of dollars, nor did he ask her why federal police or the Australian Securities and Investments Commission was suddenly searching their Sydney eastern suburbs home.

"Does the truthful answer depend on who is asking it and why?" Mr Downing said.

"No," Mr Koletti said

"Are there many truths?" Mr Downing said.

"There is one truth," Mr Koletti said.

Prime Minister Anthony Albanese has lauded late Japanese prime minister Shinzo Abe for being integral to establishing the Quad security dialogue.

Mr Albanese invoked Mr Abe's work advancing common interests in the region when speaking of the importance of Australia's relationship with Japan and the United States.

The prime minister met with Japanese counterpart Fumio Kishida and US vice president Kamala Harris ahead of the funeral in Tokyo.

Mr Albanese thanked the US for its interest in, and support for, the region.

"We live in uncertain times, there is strategic competition. It is something we are very conscious of in the Pacific," he said.

The US recently passed the Inflation Reduction Act, providing hundreds of billions of dollars for climate action.

"We believe the combination of the two will accelerate the work our two nations can do," she told the prime minister.

"That will be to the benefit of the people of our two nations and the benefit to people around the world."

Speaking at the start of a bilateral meeting with Mr Kishida, Mr Albanese said the two nations were working towards a free and open Indo-Pacific.

"(It) is so important we continue to work together and to work with our partners as well to advance the common interest," he said.

Mr Albanese offered his condolences for the death of Mr Abe, saying there was a high-level attendance from Australia "to pay our respects and show our respects to not just his family but to the people of Japan".

Mr Albanese is in Tokyo with former prime ministers John Howard, Tony Abbott and Malcolm Turnbull to pay tribute to Mr Abe, who was assassinated in July.

Mr Abe was Japan's longest-serving prime minister, from 2006 to 2007 and 2012 to 2020.

He was instrumental in elevating Australia's relationship with Japan to a special strategic partnership and central to the formation of the Quad partnership involving his country, Australia, India and the US.

His funeral will take place at the Nippon Budokan.
