Yes, I'm not sure of the types but I have a palm that is 10 ft and growing, it used to be in a pot but where I am now living it is warm enough to plant in the ground, my neighbour has palms that are around 30-40 foot.
The ecological range in Australia is enormous. The Top end, the Northern territories and North Queensland are tropical, Adelaide where I am is Mediterranean. Tasmania, where Karen lives, is northern European. We also have a total difference in rainfall, it is now monsoonal in the tropics, and drought where I am. There are floods in Queensland and we haven't has significant rain for months and we won't until May or August
People sort of forget how big Australia is. It is larger than the USA, and would be larger than Europe. I think. We just don't have many people and the major internal areas are desert.
