I would say English is more useful in the world compare to Chinese. Australia is also a more relaxing country. However if you really want to learn the language, no matter how hard it is you can do it! About the cost, Australia is definitely more expensive than Taiwan. The other thing is that in Australia, you can choose to do Mandarin as a subject so which means you can learn both languages at the same time. (not sure about Taiwan)
I think you should think about:
-where would you prefer to go
-your economic status at home
-where are you going to live
P.S. I am studying in Australia.
參考: myself.
