A solo adventurer who tried to row from Peru to Sydney has safely arrived in NSW after being rescued by a tug boat.

Alexandro Bellini's wife telephoned Water Police at 12.15pm (AEDT) on Friday, advising them her husband was 65 nautical miles off Laurieton on the NSW mid-north coast and needed help.

The 30-year-old lone rower had contacted his wife warning that he was nearing exhaustion.
