Usually preferring to explore by walking when traveling, the only time I've ever taken a city cruise bus was when Aimee and I were in London, thinking that the best vantage spot for taking photos and experiencing the sights would be up top in the open. Oh la! We were unaccustomed and unprepared for the weather, it was soo cold our teeth were actually chattering :) Not likely to happen aboard the City Sight Seeing bus or tram in Perth where even in winter the temps are pleasantly mild. Below a travel triple!
Or if you're more into train travel.. Andrew, you'll enjoy getting around and about from Perth Central Train Station in the city..
Don't forget these fab London look-alike taxis, every time I see them around the city and suburbs I think I'd like to investigate more, maybe one day I'll catch the train into the city and one of these little lovelies home :) Happy travels, take care and stay safe..
