I'm here in CNS for Oz Fest, and the welcome dinner was at Dundees. The setup was pay at the front when leaving, and the Tyro branded Worldline Yomora terminal presented a DCC prompt when I tapped my card. The DCC option was the top right button, and the local option was the top left button. Unprompted, the cashier said, "I would choose Australian dollars."

I wasn't expecting DCC, so I didn't get a photo of the prompt. Based on a mental note of the USD amount, the DCC markup was 4.5%
