Do you have enough water in your part of Australia to grow hostas? They DO like quite a lot of water, but must also have good drainage. If not, I'd choose only a couple of varieties and choose them carefully and keep them well watered. As Gerry said, there are many, many interesting varieties. You do need to decide what you like best in hostas and then go from there. They come is all variations of green (several tones), blue, yellow and white and vary from a few inches at maturity to huge.
As far as your list, I have only 'Francee' and it's a good reliable grower, but not overly exciting.
