The royal tour down under is set to go ahead as normal following news of Meghan Markle's pregnancy.

Kensington Palace has announced the Duke and Duchess of Sussex will welcome a new member of the Royal Family in May.

The couple will be officially welcomed to Sydney by Australian Governor-General Peter Cosgrove and Lady Cosgrove this morning.

Australian correspondent Donna Demaio told Kate Hawkesby their engagements are apparently going ahead as planned.

"They are also coming to Melbourne and they are going to visit Taronga Zoo, so I dare say there is going to be a photo with a koala at some point, but all sorts of things are still happening."

All up there are 76 engagements on the tour which also takes in Fiji, Tonga and this country.
