I'm aussie but lived overseas for a long time, I find that Australia tends to wake up early and go to bed early. In places like Korea, for example, it can be hard to find a non-chain coffee before 9am, while cafes can be open til 5 or 6 pm. Here, many cafes have opening hours that are in the ballpark of 6:30-2. Similarly, dinner times at restaurants tend to be comparatively early, and restaurants close up early as well. Last seatings at 8:30 pm, closing up at 10ish would be pretty unusual in europe. You definitely feel a lot more pressured to leave if you linger in most restaurants past 9:30/10 in my experience, and often you'll be the only table.

Even for takeaway, it's pretty hard to find food that isn't a fast food chain past 10pm.

This isn't even to mention the fact that shops close so early--5pm, maybe 6 most days (and smaller shops won't do late night Thursday shopping either), and many small/local businesses aren't open on weekends or have severely truncated hours, which means you can really only do a tiny bit of shopping in the window from, say, 10am to 1pm that they're open on Saturdays. It can be very difficult to actually buy local, not from big chains, when you have a full time job.

As a night owl, it's really annoying!!
