The prime minister is leading an Australian delegation to attend a series of official events before the Queen's state funeral early next week.
A small group of "everyday Australians" is among the travelling party.
Opposition Leader Peter Dutton said the outpouring of emotion for the Queen was obvious and it was great the Australian delegation was able to represent the country.
But he could not resist a light-hearted joke when asked about catering aboard the VIP jets.
"Maybe the mini-bar on the plane might be a bit diminished by the time it returns," Mr Dutton told Nine's Today Show on Friday.
Thousands of people have joined a kilometres-long line stretching across London to pay respects as Queen Elizabeth II lies in state at Westminster Hall.
Australian traveller Tiffany Wertheimer spent more than seven hours in a queue to say farewell to the late monarch.
"I arrived at the back of the queue which was a really weird feeling, obviously many more people joined immediately, but for that split second I was at the back of an enormous queue that runs through central London," she told 2GB radio.
"I've had a few moments when I was going to call it quits."
Closer to home, debate about the future of the monarchy in Australia continues, despite Mr Albanese insisting it is not the right time to address the matter.
Former prime minister Julia Gillard said following a symbolic end of an era with the Queen's death it was natural for Australians to reflect on any wider significance.
"I've always thought inevitably when the reign of Queen Elizabeth came to the end that people would reflect, but people will do that in a very measured and unhurried way," she told BBC radio.
Ms Gillard, a self-described "lifelong republican", said Australians could expect to have a discussion on constitutional change in the coming years but agreed now was not the time.
"The last time the nation considered becoming a republic that did not succeed largely because there was disputation about the model," she said.
"There are things that need to be worked through and discussed, and that can be done in a very measured way over time."
While in London, the prime minister will meet with British Prime Minister Liz Truss and his Canadian counterpart Justin Trudeau.
Mr Albanese is expected to view the Queen's lying in state at Westminster Hall and sign the official book of condolence.
A day of mourning will be held in Australia on September 22, after Mr Albanese returns, with a public holiday to mark the occasion.
Parliament will also meet on September 23 to allow the prime minister, opposition leader and MPs and senators to speak on a condolence motion.
