Woods went "down under" to serve as best man for his caddie and old friend Steve Williams, a champion driver in New Zealand when he is not on the tournament circuit with Woods, the BBC reported.
Woods participated as a driver in three races Monday in the Huntly Celebrity Classic. He was a blocker in the first race, won the second and emerged unscathed from the third. The event was a fundraiser for a charity Woods founded to help children.
Williams and Woods each jumped twice from the Nevis Highwire, a cable car platform suspended 400 feet above the Nevis River.
Woods, whose father has cancer, is expected to return to golf with the U.S. Open in June.
