This shit ain't Australia.

When you encounter a situation you initially thought to be pleasant and easy to go through, but once you go through it, you realise it was actually much more difficult than your original assumption.

- Damn, I wen't to a BJJ class last night and it was tough as hell.
- Told you bro, this shit ain't Australia.

- I sold my passion project to my company for more money and now I realise that I feel pretty dead inside.
- Yeah, this shit ain't Australia.
