Yes, Emmie, I did!
I included a stopover in Singapore (with a day trip into Malaysia) on the way out but the best bit was probably the few days I spent in Perth, when I first arrived in Oz, before going onto Adelaide. It's a beautiful (and very affluent) city, where the 'real' Australia (with kangaroos bounding across the roads and fantastic wildlife everywhere about) lives on.
I particularly remember a day trip I booked in a luxury mini-coach out to the Nambung National Park (150 miles north of Perth). I found out that I was the only person on the trip who wasn't part of a group of middle-aged (and very boisterous) girl guiders. They were determined that I wasn't going to be left out though; I must have sung 'Waltzing Matilda' nearly a hundred times that day!
Here's what we were going to see:

(That's a fantastic place for a picnic!)
