To highlight the plight of farmers the couple had tea with a family on their farm.
According to the report, a source revealed the Duke of Sussex has been an 'emotional wreck - but in a good way!' about the prospect of his new role.
Prince Harry and Meghan have arrived in Dubbo, where they have been greeted by local officials - and a bunch of schoolchildren who jumped up and down as their plane landed.
"You are the salt of the earth, honest, hardworking and as tough as they come", he said.
"That resilience, sense of humour, and commitment to the land, are the qualities that make you unique, you are the backbone of this country", he added, as Meghan held an umbrella over the pair.
"[Meghan's pregnancy] just makes everything that happened over the past year disappear", Samantha Markle told The Sun on Tuesday.
"You will continually be amazed how your life changes for the better once you put your hand up", said Harry.
Harry, who has spoken about his own mental health issues following the death of his mother, called on those affected by drought to ask for help.
Harry also had the opportunity to catch up with an old friend in the crowd, 98-year-old war widow Daphne Dunne, whom he proudly introduced to Markle.
Harry and Meghan were visiting the farm to discuss the ongoing effects of drought in the region, and the struggles and hardships faced by farmers.
"They seemed to understand exactly what we have been going through".
The couple will also travel to New Zealand, Fiji and Tonga on their first worldwide since marrying.
Prince Harry and Dunne met again previous year, during a day of events to mark the official launch of the Invictus Games Sydney 2018.
After telling the royal family about their baby news at Princess Eugenie's wedding on Friday, and formally making the announcement on Monday morning, 4,000 people gathered outside Sydney's Opera House to see the couple on their first walkabout of this tour.
