Preheat oven to 180°C. Line two large oven trays with baking paper.
Combine nuts, pepitas and flaked coconut in a large bowl.
Combine egg white, dukkah and salt in a small bowl; add to nut mixture. Stir until well combined. Divide mixture between trays in a single layer.
Bake for 10 minutes. Sprinkle each tray with currants; bake for a further 8 minutes or until browned lightly and fragrant. Cool on trays. Separate trail mix into small clusters. Transfer to an airtight container.
