I've got family in Australia, so have visited a lot. Without wanting to stereotype, there are cultural differences. Aussies tend to be more open and more competitive than Brits. Subtlety and cynicism is lacking in their sense of humour, so it is more of a "what you see is what you get", so Natalie will have to have got used to some of the nuances of the British pysche in terms of humour and competitiveness. However, I don't think she has much of a sense of humour anyway, and has pushed Ricky so hard that he seems to have been dulled a bit, and its all become about the dancing. If she returns as a pro I think we'll warm to her, or her to us. However I don't think she's come across that well. Canadian culture is probably more similar to British, and Katya was teamed with Phil, so she has made a better impression, and Aliona went out pretty early.
