Rower Shaun Quincey was only 30km from 90 Mile Beach at 7am, nearing the end of his epic 2200km journey across the Tasman.
Ground crews were heading up to the northern end of the beach where he was expected to land this morning.
Quincey, who set off from New South Wales on January 20 in his 7.3m boat Tasman Trespasser, had rolled at least twice, broken two oars and come close to running out of fresh water.
Ground crew members said this morning there was concern about how difficult it may be for Quincey to navigate the breakers and safely land his boat on the sand, and there was a chance he may swim ashore.
Quincey, 25, would be the second person to row the Tasman solo -- following in the footsteps of his father, Colin, who rowed across in 63 days in 1977.
