Belgium's Thomas Pieters and Thomas Detry extended their lead ahead of the final round of the World Cup of Golf, with the Irish pair of Shane Lowry and Paul Dunne now eight shots off the pace.
After strong winds and heavy rain tested the resolve of nearly all the field in round two, conditions were more benign on Saturday and the scoring reflected that in the fourballs.
The leaders shot an impressive 63 to sit on 19-under par at the Metropolitan Golf Club in Melbourne with an almost flawless round, including an eagle on the par-five ninth. They lead the field by five shots.
Lowry and Dunne posted an impressive 65 to leave them at 11-under and in a share of eight spot.
Mexico's Abraham Ancer and Roberto Diaz, climbed five places to tie for second when they posted a similar score. They sit alongside Italian pair Andrea Pavan and Renato Paratore and South Korea's An Byeong-hun and Kim Si-woo on 14-under par.
Three countries sit tied for fifth on 13-under - Alexander Bjork and Joakim Lagergren of Sweden, Australian pair Cameron Smith and Marc Leishman and England duo Tyrrell Hatton and Ian Poulter.
Reigning champions Denmark, represented by Thorbjorn Olesen and Soren Kjeldsen, are tied for 11th on 10-under, a shot behind Scotland's Russell Knox and Martin Laird.
