Kiwi golfer Brad Shilton has earned a flash new watch for nailing a hole-in-one in the first round of the Australian Open in Sydney.

Shilton was the first to hole out on the par-three 11th - his second hole of the day - to earn a $16,000 Australian dollar watch for his troubles.

He's now one-over for the tournament through six holes, tied for 65th and nine shots off leader Cameron Davis.

Ben Campbell's the best of the New Zealanders, four back from the lead in a tie for fifth.
