The royal couple announced Meghan's pregnancy on Monday, hours after she and Harry landed in Sydney as part of a 16-day tour that will also visit New Zealand, Fiji and Tonga.
The conversations about the future baby have been largely silenced during the first days of the trip, but the UK Press Association revealed that the children who accompanied them on their tram trip were able to ask the questions the journalists had not asked.
Twelve-year-old Charlie Wolf pressured the couple on the name they would give their son and told PA that Meghan replied, "We have received a long list of names from everyone, we are going to sit down and have a look at them. . "
Meghan, 37, and Harry, 34, then took the tram to the beach to meet lifeguards and volunteers from Beachpatrol, an organization that keeps beaches clean.
The video images show Meghan and Harry greeting the children of the local schools, who gathered to welcome them.
At the beginning of the day, the couple visited the Royal Botanic Gardens, a community cafe and a primary school, before seeing an Australian football exhibition of members of the This Girl Can rating campaign.
The sport is very popular in Melbourne and in the rest of the state of Victoria, and Meghan captivated the spectators while throwing a successful pass after a bit of encouragement from the crowd.
The couple is also scheduled to watch the Invictus Games in Sydney, an international sports competition for wounded veterans and members of the armed forces initiated by Prince Harry in 2014.
The couple began the first day of their first Australian tour with an official welcome ceremony at Admiralty House in Sydney, where they were presented with some quintessential Australian gifts: a pair of Ugg baby boots and a kangaroo doll.
They then visited an agricultural area of New South Wales, in distress and affected by the drought, after going through the Royal Flying Doctor Service (RFDS), a lifeline for many in the vast rural areas of the state, to discover a new plane.
According to PA, the tour will move to the largest city in Australia on Thursday with an escalation in the Sydney Harbor Bridge and meetings with Prime Minister Scott Morrison and opposition leader Bill Shorten.
