I noticed DCC at the Machi Machi Darling Square location tonight. There was a Tyro Payments Yoximo terminal. While I hadn't been to this location before, other locations of Machi Machi did not have DCC during my last trip two years ago. The on screen offer claimed to be a 5% markup, but it was more like 7.6% compared to Visa's rate. One interesting thing that I noticed was that there was a sign saying that the terminal wouldn't work with non-Australian cards. I had no problem tapping my payment card, but perhaps it's been an issue with people inserting cards and having the transaction fail due to lack of PIN as a CVM. I noticed that the terminal at the counter was customer facing, so I'll give it the benefit of the doubt that the sign wasn't due to there being DCC present.
