WhyGo Australia travel writer Brooke Schoenman said this is a "great place to raise a family".
There are a significant number of museums and Questacon, which is an interactive technology and science centre, she continued.
School pupils often visit these on excursions and days out, the writer added.
Ms Schoenman argued that this city might not be quite as child-friendly as the Gold Coast, which is "littered with theme parks and water parks".
These include Dreamworld and Seaworld, although there are many good locations for youngsters across the country.
Scuba-diving or snorkelling in the Great Barrier Reef was recommended by the expert, who called this "one of the most worthwhile" activities to undertake with children.
Youngsters, mothers and fathers alike often feel like it is "a scene from Finding Nemo", she asserted.
Animal enthusiasts may also wish to visit the wildlife habitats that exist along the east coast of the country, such as in Port Douglas or on the Gold Coast.
"Families can feed kangaroos and hug koalas" in these places, Ms Schoenman explained.
Late television personality and animal lover Steve Irwin's relatives work in the Australia Zoo, which can be seen as part of a road trip.
"Interesting roadside attractions" include the Giant Mango and the Big Banana – some of Australia's 'big things' that are often visited as part of voyages across the continent.
The expert said: "Any sort of road trip can be a family-friendly activity".
The US state department notes that Australia has strict quarantine laws to ensure foreign materials and diseases that pose a threat to its wildlife do not enter the country.
Furthermore, many creatures in the country can pose a risk to humans, including poisonous insects and snakes.
Jellyfish, sharks and crocodiles have also been known to harm people and the government body states: "The continent and its waters host wildlife that merit awe and respect in equal doses."
