Q.Do winged beans grow in Sydney, Australia?
I have a strong liking for winged beans and am considering planting this much sought after vegetable in my backyard.

Sydney is in a warm temperature zone. Winged beans are more ideally grown in tropical zones that are hot and wet with 60-100 inches of rain or irrigation per year, so I am thinking you might have disappointing results.
