The Duke and Duchess of Sussex have made no changes to their Fiji schedule despite the presence of Zika virus in the country.
Prince Harry and Meghan Markle will touch down in Suva this evening for an official welcome at the airport before heading to Albert Park just outside Parliament.
There the royal couple will enjoy a "mirror image" of the ceremony the Queen and Prince Philip had when they visited Fiji in 1953.
Royal correspondent Melissa Davies says it doesn't look as though they've altered their Fiji schedule to take into account the risk that Meghan could contract Zika.

The virus, of which there's evidence in Fiji, is transmitted via mosquito and can be passed from a pregnant woman to her unborn child.
The International Association for Medical Assistance to Travellers advises that women avoid travelling to Fiji during their pregnancy.
That doesn't seem to have stopped Harry and Meghan, who will attend a number of engagements over the next three days.
Davies says it looks as though the couple, who have considerable influence over their schedule, planned the Fiji leg of the tour with pregnancy in mind.
"I think they were thinking either perhaps she would be pregnant or she would be trying to get pregnant at the time, I think they'd thought about that before they put the schedule in place," she told The AM Show.
She says evidence of premeditation can be seen in their schedule for Wednesday. The couple will go their separate ways, with Prince Harry heading into the mosquito-heavy bush while Meghan takes a rare solo trip to Suva markets.
The Fiji Government took out an ad in The Fiji Sun stressing the royal visit is being hosted by President Jioji Konrote and has "nothing to do with politics". The country has an election in 20 days.
