✔ 最佳答案
The present perfect tense is used for actions or events taking place in the past and continuing into the present or very recently completed. Your first two examples fall into the "very recently completed" category, but you can just as easily use the simple past tense. There is no real difference in meaning.However, your studying in Australia is an ongoing action still current, so the present perfect must be used.
