刚到悉尼那周，我因为48小时没回导师的约见邮件，被私信提醒‘Please be mindful of communication expectations’——那一刻我才明白：在澳洲，不及时回邮件=不专业。
? 邮件时效：不是越快越好，而是要在“黄金窗口”内响应
- 学术邮件（教授/TA）：建议24小时内回复，哪怕只是写一句‘Thank you for your email. I’ll prepare the materials and reply in detail by tomorrow.’ 举个真实案例：墨尔本大学工程系有位博士生因超过72小时未读邮件，课题组会议资格被临时取消。
- 行政事务（选课/签证/住宿）：学校部门通常承诺3个工作日内答复，你应在此基础上+1天缓冲期回应。比如ANU住房办公室发来确认信，最好在48小时内确认入住意向，否则床位可能释放给候补名单。
- 实习/求职沟通：HR邮件必须12小时内首响！去年布里斯班一家科技公司招聘实习生，两名候选人能力相当，最终录用的是当晚9点回复‘Available for interview tomorrow’的人。
? 内容格式：别用中式客气话，澳洲人要的是“清晰+直接”
我第一次给UTS导师发邮件用了‘您好，打扰您宝贵时间……万分感激’，结果收到回复：‘Please state your request clearly in the first paragraph.’ 后来才懂规矩：倒金字塔结构才是王道。
Subject: Request for Extension on BUS700 Assessment Due 15 Apr
Dear Dr. Wilson,
I’m writing to request a 3-day extension for the BUS700 literature review (due 15 Apr), as I’ve been unwell with confirmed medical leave from 8–12 Apr (certificate attached).
The draft is 80% complete, and I aim to submit by 18 Apr. Please let me know if this is acceptable.
Best regards,
