The royal couple are in talks with Prime Minister Scott Morrison to negotiate the details of the trip before he extends an official invitation, it was announced last month.
However the trip could be delayed due to coronavirus fears, according to the Herald Sun.
The Cambridges prefer to travel on commercial planes and attract large crowds, potentially putting them and the public at risk of contracting or spreading the virus.
Kensington Palace declined to comment when contacted by Daily Mail Australia.
The Prime Minister’s office is not believed to have any official word about changes to the plans but said it doesn’t comment on arrangements considered by potential guests.
The royals have not given much away about their trip, which has not been officially announced, but it is believed they will visit bushfire ravaged communities in Victoria and the New South Wales coast.
Despite the concerns surrounding coronavirus, the Duke and Duchess continued with their tour of Ireland this week.
In January the couple gave their heartfelt condolences to everyone impacted by the fires that raged since September 2019.
‘We continue to be shocked and deeply saddened to hear about the fires that are destroying homes, livelihoods and wildlife across much of Australia,’ the couple wrote on Instagram.
‘Our thoughts and prayers are with all the people and communities who are affected by this devastating event.
‘We send our deepest condolences to the families and friends of those who have tragically lost their lives, and the brave firefighters who continue to risk their own lives to save the lives of others.’
The Queen and Prince Philip issued similar sentiments.
Daily Mail Australia has contacted the Prime Minister’s office for comment.
