Simon Dorante-Day, a British-born engineer who settled in Australia after being adopted, appeared on Sunrise claiming his son is the spitting image of a young Queen Elizabeth.
‘I think the evidence speaks for itself,’ Mr Dorante-Day told hosts David Koch and Natalie Barr on Tuesday morning.
Mr Dorante-Day, who resides in Queensland, snapped a photo with his son Liam, 14, last week while on a fishing trip at Bribie Island.

He then shared the image to his Facebook page, where he often posts about his alleged blood relation to the royals.
‘I just shared it with the people on the page and a lady took the photo and changed it into black-and-white and rotated it and put it alongside the Queen,’ Mr Dorante-Day said.
‘I said every day, when I get up in the morning and the kids speak to me, the first thing I see when I turn around, is that, so it is always in my face.’
Barr replied: ‘I know it is a likeness but I don’t know whether that is proof’.
The Sunrise host questioned how Mr Dorante-Day, who was conceived in 1965, could prove his claims when royal commentators say Charles and Camilla met in the 1970s.
Mr Dorante-Day said his grandmother told him about his alleged connection to the Duke and Duchess of Cornwall back in 1998.

‘One of the first things we did was get all the biographies that we could at the time and look this thing up and look at the times to see where Charles and Camilla were, who otherwise could be involved,’ he said.
‘Just because your grandmother said it doesn’t mean you are going to believe it.
‘I did do my research, so the timelines are gaps, people need to come forward and come clean.’
Mr Dorante-Day, who said his birth certificate is ‘complete rubbish’, intends to take his claims back to court.
‘I have a lot of evidence and I’m slowly collecting more. The longer this thing runs the more they are going to get egg on their face, not me,’ he said.
Mr Dorante-Day shared the image comparing his son to Queen Elizabeth a week ago.
‘I’m going from seeing young Charles in Liam to her Maj… Too good not to share,’ he wrote.

Facebook users following Mr Dorante-Day’s quest for answers commented on the post, declaring they could see the likeness.
‘Wow even his precious little eyes look like Queen Elizabeth! And the jaw lines,’ one person commented.
‘Yes, I saw the resemblance of Liam to Elizabeth in the photo you shared today and thought, wow!!! Too many similarities between yourself, your children and others for it to be a mere coincidence,’ another wrote.
Mr Dorante-Day claims his adoptive grandparents Winifred and Ernest worked for the Queen and Prince Philip as a cook and a gardener respectively and told him ‘many times’ that he was ‘Charles and Camilla’s child’.
He said previously: ‘I know it sounds unbelievable, but anything I say is checkable… I’m simply a man looking for my biological parents, and every road has led me back to Camilla and Charles’.
Mr Dorante-Day was born in Gosport, Hampshire in April 1966 and was adopted when he was 18-months-old by Karen and David Day.
If his bizarre allegations are true, he would have had to have been conceived in 1965, when Charles was 17 and Camilla, 18, and he claims his Windsor-like cheek-bones and teeth, and ‘Camilla-style hair’, is compelling evidence his claims are true.
