NSW "Clubs" ("Registered Club" or "RSL Club") are required by legislation to record entry. Pubs aren't, and nightclubs would only bother if they've had a major insurance claim and were trying to avoid hikes in their premiums.

What an "RSL Club" is, and the nexus of legislation and idiotic operational rules attached to their tax free status, can be a little too difficult to explain to an American. But operationally it's similar to a Native American reservation casino with the same negative social effects on the surrounding community.
