The new parents are also allegedly taking their baby, Prince George on the month-long visit, who will be nine months old by the time they take to the skies.
Kate and William want to be able to give their young son some stability on the trip, which is one of the reasons they have chosen to temporarily settle in the Australian city.
The Sydney Morning Herald has reported that arrangements are being made locally to welcome the royal couple. 'An advance party of royal aides will arrive in Sydney this month to finalise precise details of the expected month-long itinerary', wrote the paper.
'One key issue is secure accommodation where the then nine-month-old Prince George, third in line to the throne, can be cared for while the royal couple meet what is likely to be a gruelling program.'
Although Kensignton Palace have issued a statement confirming the Duke and Duchess' trip, no details of their schedule have been released.
'Their royal highnesses have been invited to visit by the New Zealand and Australian governments. Further details on the exact dates and itinerary will be issued in due course,' said a press release last year.
Kate and William will be following in the footsteps of Prince Charles and Princess Diana, who also visited Australia and New Zealand in 1983. Prince William, then aged 9 months, also accompanied his parents Down Under.
Will this be Prince George's first trip abroad? We'll have to wait and see...
