澳大利亚之旅第五天 - 初抵悉尼见闻
Australia Trip Day 5 - First Impressions of Sydney
2024年4月11日，我们乘坐航班从凯恩斯飞往悉尼。令人惊讶的是，前往机场时叫到的Uber竟然是与之前相同的三菱欧蓝德车型，只是司机不同。这次车费仅25.53澳元，相比上次夜间时段的42.84澳元实惠许多。
On April 11, 2024, we flew from Cairns to Sydney. Surprisingly, the Uber to the airport was the same Mitsubishi Outlander model as before, just with a different driver. This trip cost only A$25.53, much cheaper than the previous night-time fare of A$42.84.
悉尼公共交通初体验
First Experience with Sydney's Public Transport
尽管悉尼官方宣传支持信用卡直接乘车，但我们的Visa和Mastercard都无法使用。我们注意到许多外国游客也遇到了同样的支付问题。最终我们选择了购买Opal交通卡（最低充值金额为35澳元）。
Although Sydney officially promotes credit card payments for transit, our Visa and Mastercard didn't work. We noticed many foreign tourists facing the same payment issues. We ultimately purchased Opal cards (minimum top-up of A$35).
重要提示：悉尼所有公共交通都严格执行上下车刷卡制度，包括：
Important Note: Sydney strictly enforces tap-on/tap-off rules for all public transport, including:
- 火车、地铁、轻轨
- Trains, metro, light rail
- 渡轮、电车和巴士
- Ferries, trams and buses
忘记刷卡可能面临高达200澳元的罚款！
Forgetting to tap can result in fines up to A$200!
背包客栈住宿体验分享
Backpacker Hostel Experience
我们选择入住市中心的背包客栈，这类住宿具有以下典型特征：
We chose a downtown backpacker hostel, which typically features:
- 共享生活空间：厨房、洗衣房等设施为公用区域
- Shared Living Spaces: Communal kitchens, laundry rooms and other facilities
- 自助服务模式：旅客需要自己准备餐食和保持清洁
- Self-Service Model: Guests prepare meals and maintain cleanliness themselves
- 多元文化交流：来自世界各地的旅行者在此相遇
- Multicultural Exchange: Travelers from around the world gather here
- 黄金地理位置：通常位于市中心或主要景点附近
- Prime Locations: Usually in city centers or near major attractions
客栈的公共厨房是最有趣的社交场所，可以看到各国旅行者烹饪家乡美食。储物系统也别具特色：每位客人有专属储物格，未用完的食材会放在公共区供他人取用。
The communal kitchen is the most interesting social space, where you can see travelers cooking their native dishes. The storage system is unique too: each guest has a personal locker, with unused ingredients placed in shared areas for others.
在这样轻松愉快的氛围中，我们度过了悉尼的第一天。接下来将深入探索这座南半球最繁华的都市！
We spent our first day in Sydney in this relaxed atmosphere. Next, we'll explore this most vibrant city in the Southern Hemisphere in depth!
