Laminate benchtop repair

See photo. Laminate benchtop has water damage. The benchtop is high pressure laminate from Mitre10, Only installed a year ago. Just wondering if a repair is possible without having to replace the whole benchtop. I had purchased subway tiles and was going to put a splashback around the edges but didn't get round to it. . Maybe if I had done that I wouldn't have this problem. I had some Air BNB tenants in and I think they must've left a wet towel on the edge or something. Thanks
