Barnes is a place in south-west London in the London Borough of Richmond upon Thames.
It is the seat of the barony for Christopher Francis Patten, Baron Patten of Barnes.
The only permanent tourist attraction in Barnes is the WWT London Wetlands Centre, next to Barn Elms, comprising over 40 hectares of artificial wetlands created on the site of a former reservoir as a bird sanctuary.
The 23-year-old, from Muswellbrook in the NewSouthWales Hunter Valley, spread nine birdies into his round of 6-under par 65 to lead Western Australia's Greg Chalmers, Victorian Richard Green and Queensland's Rod Pampling, who all carded 67s.
Barnes won the Australian amateur championship two years ago then quit his job as a storeman 12 months later to follow his dream of scratching out a living as a professional.
Playing in the afternoon when the wind was lighter, Barnes made a shaky start, with a double bogey on the third and a bogey on the next hole, but reeled off four birdies on the trot to go out in 2-under 33.
