Jason,
The wife and I went to Australia about 10 years ago. Started in Sydney where I gave a speech to the Australian Club Managers Association. That group invited us along to their golf outings at Royal Sydney, Australian Club, New South Wales, and a few others. All worthwhile, but I wanted to see the Sandbelt, of course.
My wife wanted to stay in a bed and breakfast in Melbourne, and I was concerned about travel time to the famous courses, but she booked one through the b and b agency there. We got there, made small talk about two minutes, and then I had to ask where we were in relation to RM. The lady pulled back her curtain and said, "Why its right there out back!"
So, we lucked out big time. The gent even drove me around to the other courses not within walking distance.
Since many of these are simply retired couples in typical houses just wanting to make some extra money, you might consider the b and b route. We had a great time talking with this older couple at night, and I felt it gave us a chance to learn more about the real Australia. Wife pleasing and cheaper to boot, especially if you had to rent two hotel rooms for your family!
