The prime minister confirmed the meeting on Tuesday when he announced the names of 10 "everyday Australians" who will represent the nation at Monday's state funeral at Westminster Abbey.
The list includes champion racehorse trainer Chris Waller, wheelchair tennis star Dylan Alcott, this year's Senior Australian of the Year Valmai Dempsey and 2021 recipient of the award Dr Miriam-Rose Ungunmerr Baumann.
Australian of the Year Local Hero Shanna Whan and state finalists from Queensland and Tasmania Saba Abraham Kim Smith will also attend, along with South Australian Young Australian of the Year Trudy Lin.
Co-creator of the i4give Foundation Danny Abdallah has also been invited as well as Professor Helen Milroy, the 2021 Western Australian winner of Australian of the Year.
Mr Albanese said the 10 people represented each state and territory.
"The Australians who have been invited embody an extraordinary contribution to our nation," he told reporters in Canberra.
"We have made sure that all eight (jurisdictions), six state and two territories, are represented, that there is an appropriate breadth of Australians as part of the delegation."
The 10 people will leave Australia for the funeral alongside Australia's official delegation, which include the prime minister and his partner Jodie Haydon, Governor-General David Hurley and his wife Linda, and acting high commissioner to the UK Lynette Wood.
Mr Waller, the thoroughbred trainer of champion mare Winx, looked after many of the Queen's horses and built a close relationship with her over the years.
"She was very normal and made you feel very comfortable," he told Nine's Today Show.
Mr Alcott, who famously made the Queen giggle during a Zoom call after being named Australian of the Year, will also attend the funeral.
RSL Australia president Greg Melick will attend on behalf of the organisation, of which the Queen was a patron.
"For the past seven decades, every person who enlisted in the Australian Defence Force swore an oath to serve Queen Elizabeth II and her heirs and successors so it is fitting we are now able to personally express our condolences," he said.
Arrangements are being made for Mr Albanese to meet with a number of world leaders while in London.
Meanwhile, he hosted diplomats from 24 Commonwealth nations at The Lodge on Tuesday morning to commemorate the Queen.
Mr Albanese said it was important for Commonwealth nations to be able to mourn the late monarch.
When he returns from London, Australia will have a day of mourning on September 22 which will include a national memorial service at Parliament House.
The short notice about the public holiday has sparked concerns about the impact on surgeries and small businesses.
However, Mr Albanese hosed down the concerns, saying the day of mourning was the right decision.
"I'm sure that these issues, with a bit of common sense, can be worked through. If someone needs chemotherapy on that day, of course, they should receive it," he said.
"If you're a small business owner in hospitality there will be an enormous amount of activity on that day, I should imagine."
Victorian MPs will be re-sworn and a condolence motion held on Tuesday before state parliament adjourns to next week as a mark of respect.
The re-swearing of senior public office holders and members of parliament following the death of the reigning monarch is unique to Victoria's constitution.
Other state parliaments will also sit on Tuesday to hear condolence motions before adjourning.
Mr Albanese also confirmed some Pacific nations have accepted an offer from Australia for transport to the state funeral in London.
Details are set to be announced of which Pacific leaders will travel with the Australian delegation in coming days.
