Yup, Perth does have Miniature Golf! They don’t always call it mini golf, but it is Mini Golf ;)

Here are some places where you can play mini golf and do other things as well:

 

Wanneroo Botanical Gardens, Home to Botanic Golf and Leap Frogs Cafe

Hillary’s Boat Harbour
Here you can do much more than just mini golf! They have an aquarium, a water park with slides for the kids, restaurants, cafes, shopping outlets, a chocolate cow shop, and much more! The shops and restaurants are open till late (I think around 9pm). You can eat made to order food and walk on the jetty based boardwalk and visit the shops on the water.
