Staff would not budge when work permit and driving license were presented.
Also to note… We followed the QueQ app as required, however, when we arrived we weren’t asked about this at all. We paid, were told no swimming and that was it. We spent a lovely 2.5 hrs in the park. Hiking up to the 7th waterfall, getting our feet wet and enjoying the peace and quiet (it was getting much busier on our way down. We arrived at the park at 10.00am)
