They are expected to visit New South Wales and Victoria, however, planning is not finalised and other states including South Australia may be added.
Kensington Palace declined to comment but an announcement is expected within weeks provided there are no last-minute changes to their schedule.
William’s visit to Queensland in 2011 took place about two months after the peak of the disaster, while a lightning trip to New Zealand last year occurred six weeks after Australian man Brenton Tarrant allegedly shot dead 51 people in a mosque and Islamic centre in Christchurch.
The 37-year-old, who is second-in-line to the throne, and his 38-year-old wife are the most popular members of the British royal family after the Queen. A YouGov poll of more than 6000 people taken between January 2019 and January 2020 showed 65 per cent of the British public had a positive opinion of Prince William, while 64 per cent had a positive view of Catherine. Less than 10 per cent held a negative opinion of the pair.
The tour has the potential to raise more international donations for the recovery effort given the couple’s high profile and massive following on social media.
It is not clear whether their three children – Prince George, 6, Princess Charlotte, 4, and Prince Louis, who is nearly two – will also make the trip.
The unprecedented fires gripped the UK and triggered protests outside Australia House in central London over the link between climate change and extreme weather events.
William and Catherine, the Queen and Prince Philip, and Prince Harry and Meghan, the Duchess of Sussex, issued separate statements in early January expressing shock at the death and destruction in Australia.
Harry and Megan, who have since stepped back from royal duties and moved to Canada, warned the globe was facing an environmental crisis described as “ecocide”.
The royal family also made a dramatic intervention over the effects of climate change, warning the Earth was at a “tipping point”.
Launching “the most prestigious environmental prize in history” on New Year’s Eve, William said humans faced a “stark choice”.
“Either we continue as we are and irreparably damage our planet or we remember our unique power as human beings and our continual ability to lead, innovate and problem-solve,” he said.
His Earthshot Prize initiative will aim to uncover solutions to climate change across all parts of industry and society. Drawing comparisons to the Nobel peace prize, multimillion-pound prizes will be awarded to five winners each year over 10 years. Recipients could include scientists, activists, economists, political leaders, governments, banks, businesses, cities and even countries.
