Santos' surge helped boost the energy index 2.1 percent, even as oil prices declined amid lingering concerns over slowing global growth that may weigh on fuel demand. Aussie financial stocks edged up 0.5 percent, with index heavyweight Macquarie Group Ltd climbing 1.4 percent. Macquaire snapped three consecutive sessions of losses. However, uncertainty over the partial US government shutdown, global growth and the yet-unresolved trade standoff between the United States and China capped gains.
The metals and mining index extended its losing run to four days, shedding 0.3 percent. The world's biggest miner BHP Group dipped to its lowest close in nearly three weeks, while South32 Ltd fell 0.9 percent. Gold stocks lost the most, sliding 2.3 percent with Northern Star Resources Ltd dropping 5.4 percent, while St Barbara Ltd lost 4.7 percent.
New Zealand's benchmark S&P/NZX 50 index closed flat or up 2.88 points to finish the session at 9,108.91. Fuel distributor Z Energy Ltd and telecommunication and digital services supplier Spark New Zealand Ltd were amongst the top percentage gainers, jumping 2 percent and 2.7 percent, respectively.
