When I moved to Australia it was weird not to leave tips in restaurants. I was still used to the 15-20% standard at home. On a related note, I also found the service at many establishments awful. It was frustrating, and then I found myself getting more frustrated for allowing such a silly thing to bother me.
A year and a half later, I’m mostly over it. Instead of being fed up with bad service, I appreciate really awesome service when I experience it. It’s something to celebrate rather than just have to expect in a tipping culture. Good service is genuine here. When someone is friendly and goes out of their way it makes me smile. I love that feeling.
I’m also happy not to tip. Stuff here is expensive enough already. I don’t need to add a 20% on top of that. As a general rule, I do still leave a small tip at nice restaurants for exceptional service. I’m really curious on what percentage of Australians tip at restaurants, and how much.
What is your experience with tipping and customer service in Australia?

Just thought I might satisfy your curiosity, as an Australian, by saying that the majority of us never tip. Hospitality workers get an acceptable wage, and we certainly pay enough for the service already.
That aside, I think it’d be nice if the prices were cheaper and we expected to tip as it encourages better service (also, my friends who work in hospitality love when they serve Americans, as they are much more likely to get a tip even in Australia!)
