After the cut scene that begins this mission, speak with Mario and meet with Dimah. You’re instructed to seek out a contract, but that’s not your most pressing task. As the mission begins, head across the river to meet Mario’s friend next to the boat. Tether the boat to the nearby sand bar to pull it into the water, then Fast Travel to the location near Manaea.
Using Fast Travel completes the mission and unlocks the Fast Travel ability. To begin the Conflicting Interests mission, head to north of Manaea to Vigilator Nord.
From here you can continue on to the Conflicting Interests mission or head back to the Just Cause 3 hub for more information on the game.
