Hi,
You are so right, For some reason people on this site seem worse than most. People don't even read the question or your reason for asking it as you can see from the above!
For me I am married to an Aussie but fell in love with the place when I worked there in 2000. I love the weather, being able to plan days out without worrying if it will rain. I love the work, I love the massive nature of the place, driving up North and camping under the stars. If you head out from Perth a little the stars at night are simply astonishing.
You can only decide for yourself whats best, I would suggest ignoring 99% of whats on this site and go experience things for yourself - from your question I can see you have the right attitide to succeed.
