Harry and Meghan have announced they will be embarking on a pseudo-royal tour of Australia in mid-April. But do the Sussexes realise that they might be heading for a blunder Down Under?
Their last trip to Oz was in 2018, when the newly married Sussexes - who had announced they were pregnant with their first child the day before touching down - were welcomed by cheering monarchists waving Union Jack flags and throwing kangaroo paws flowers and roses in their path.
But if they think this trip will be anything like those heady days, they are in for a rude awakening.
Even before they arrive, questions are already being asked about why non-royals Meghan and Harry are visiting their country when the last time they saw King Charles and Queen Camilla was two years ago, and Prince William and Princess Catherine not since 2014.
Visit Could Reignite Australia's Republican Debate
So much for the special relationship with their Head - and future Head - of State.
Indeed, constitutional experts in Oz predict Harry and Meghan's visit will provide 'a lightning rod' for Australia's republicans, igniting further debate about whether King Charles should remain their head of state - or, shockingly, whether they need one at all.
Inevitable questions are being asked about why there haven't been more frequent visits by senior members of the Royal Family. With the King's ill health and Kate's recovery from cancer, the spotlight has been thrown on to Prince William. Some are rudely asking online: 'Does William even want to be our next Head of State or not?'
Others question, quite understandably, what relevance either Charles or William has to a modern Australia when they live half a world away.
Australia's Attitude Towards the Royal Family Has Changed Since 2018
It was surely not the Sussexes' intention to cause discomfort for Charles or William. Harry is there to further his involvement with the Armed Forces and veteran communities for his admirable Invictus Games initiatives. There are reports that Meghan is due to appear as a guest on the Her Best Life podcast, launched and co-hosted by Aussie radio star Jackie O Henderson. Perhaps she's looking to promote her As Ever lifestyle brand now her Netflix deal is over?
But I fear what the Sussexes don't realise is that the Australia they visited in 2018 is no longer a photo-op destination for royals - or indeed non-royals - to further their interests and causes or monetise themselves. And if they're expecting locals to be gushingly grateful, they've got another thing coming.
Because the reality is that the Aussie attitude towards the Royal Family has changed dramatically in the past eight years.
Royal Approval Ratings in Australia Have Fallen
When the late Queen was alive, she had an 83 per cent approval rating among Australians. But her death only heightened the now ferocious debate between monarchists and republicans - one which will flare up like an Aussie barbie with a squirt of lighter fuel when the Sussexes arrive.
Charles's approval ratings are now at only 59 per cent.
The Sussexes, as working royals, once enjoyed such approval in Oz that there were fears it would eclipse that of Prince William and Princess Catherine. But that was before they quit for sunnier shores in California. They have broken two golden Aussie rules - no snitching and no whingeing - since leaving the Royal Family and will not be embraced as they once were. Their popularity has plummeted; Meghan's ratings at 55 per cent unfavourable and Harry's at 40 per cent.
What they perhaps haven't taken on board, as I have on my frequent trips back to Australia, is that all that reverence for the royals so ingrained in both me and my parents' generation has been all but extinguished.
Arrival of Two Non-Working Royals Set to Infuriate Republicans
Few six-month pregnant women these days would run five blocks in 40C heat to catch a glimpse of the Queen passing by in her carriage, as my mum did.
That world has gone. Respect for the British Royal Family and a monarch's constitutional right to be Head of State is no longer a given. Support for it is at an all-time low. It is fragile.
Islam is now the second-largest religion in Australia. Why should Muslim communities honour a Royal Family constitutionally linked to the Church of England?
So the arrival of two non-working royals will infuriate republicans and further focus their arguments - especially among Generation Z, who cannot see the point of bowing and scraping to what they view as an antiquated concept of inheritance, wealth and privilege bestowed on people who live half a world away.
As the Australian journalist Tom Sykes wrote on his Substack, The Royalist, after the announcement of Harry and Meghan's not-royal tour, the couple are likely to stir not affection but a 'bonfire of resentment'.
He's right. Because if there is one thing I know about Aussies, we bow to no one.
