A SOUTH KOREAN artist who flew back to Australia to rebuild his popular art installation in the Biennale of Sydney after it imploded in the recent wild weather will complete his mission today.Choi Jeong Hwa’s rebuilding came as Cockatoo Island, one of the exhibition’s two main venues, drew 4844 visitors on Sunday – its biggest one-day result in a biennale – and 12,283 across the long weekend, confirming attendance is bouncing back after the wet stretch.Hubble Bubble drew much attention in its spot between two sails of the Sydney Opera House before it was damaged in heavy winds. He flew in from Seoul on Friday and worked with volunteers over the weekend to rebuild the piece, in which hundreds of neon-green colanders formed tall walls that created a twisting path to walk through.The artist and designer, who had been in Sydney for the Biennale opening just over a month ago, said he was not at all worried about Hubble Bubble being wrecked. ”I am OK … nature is more important. Art is not important,” he said. The work’s meaning was to ”think green”. Attendance across the Biennale’s seven venues over the long weekend was strong, a spokeswoman said. It reflects a return to the buoyancy of the record opening week before visits dipped when the rains took hold. This led to overall attendance for the first three weeks – the latest figures – of 122,932, a 4 per cent drop on 2008.The exhibition’s artistic director, David Elliott, said it was a strong result given the bad weather. He expected visitors to top 500,000 by the show’s end on August 1 – passing the 436,000 in 2008. ”It’s flowing the right way,” he said.Mr Elliott said Hubble Bubble had fallen victim to a ”freak” wind in a location that created a wind-tunnel effect. ”We had it checked out by a structural engineer [beforehand], of course, so we thought it was OK … but it got hit.”Choi scouted Cockatoo Island with Mr Elliott on Friday to find a less vulnerable spot to rebuild. Nine crates of the various-sized green colanders were moved in.The 49-year-old artist is expected to finish remaking the piece today with the same materials but a different design – hanging from the roof like jellyfish tentacles. ”For me it’s good opportunity,” he said. ”New location, new installation.”
