A chip-in eagle at the third hole put world No. 1 Lydia Ko back to the top of the leaderboard in the ISPS Handa Women's Australian Open at Royal Melbourne, as three leaders cleared out.
The New Zealand teenager momentarily lost the lead when she took bogey at the first hole then three-putted the par-five second.
She was overtaken by South Korea's Amy Yang, playing in the second-last group, who made a long birdie putt at the third hole.
But at the third, Ko drove it down near the green at the short par-four hole and then conjured a brilliant chip-in for eagle to reach eight-under par.
Through six holes, Ko leads by a shot from Yang. They have cleared out two shots ahead of Thailand's Ariya Jutanugarn, who is three shots back from Ko at five-under.
Australia's Katherine Kirk is tied-eighth at one-under for he tournament, while Minjee Lee (even) is tied-13th and veteran Karrie Webb is tied-15th and two-under for the day.
Ko has never won an Australian Open.
She scaled to No. 1 in the world at just 17 years of age — the youngest player ever to do so — when she finished second in a tournament in America a few weeks ago.
