Organiser Denise Mosley said people from all over Perth flocked in to enjoy hot dogs, American beer and wine and thousands of Krispy Kreme Donuts.
Vintage US military vehicles and classic American cars, including Corvettes, Ford Thunderbirds and Jeeps, as well as vintage Harley Davidsons, were on display and American goods and crafts were available for sale.
The event was run by the American Women’s Club of Perth, an organisation of international women which promotes fellowship between Americans and Australians.
Activities included demonstrations of American sports, including baseball and gridiron.
For children, there was a bouncy castle, a petting zoo, face painting and a baseball batting cage.
The fair celebrated the 4th of July, American Independence Day.
On that date in 1776, the USA adopted the Declaration of Independence, declaring the country independent from Great Britain.
In the United States, it is a national holiday and is traditionally celebrated with picnics, barbecues, parades and fireworks.
