The strongest field of the domestic summer keeps getting deeper, with three former champions committing to the 100th edition of the Australian Open.
It's been confirmed that major winner Geoff Ogilvy will be among the headliners at The Australian Golf Club next month, joining consistent US Tour challenger John Senden and perennial force Greg Chalmers on the bulging card. 
The trio will be three of 10 former winners in a field that includes the sport's hottest commodity, Jordan Spieth, Australia's green jacket hero Adam Scott, Presidents Cup aces Marc Leishman and Steven Bowditch, as well as European greats Lee Westwood and Darren Clarke.
Ogilvy will be aiming to use the event he won in 2010 to kick-start his game after a quiet season on the PGA Tour, and notch just his second victory in the past five years.
This year's Australian Open looms as important for Ogilvy, given his just completed season in the US ended with only one top-10 finish and a respectable showing at the US Open, where he finished tied for 18th.
A reduced schedule (his 16 events in 2015 is on track to be the lowest number Ogilvy has played in a calendar year since reaching the PGA Tour in 2001) has generated a return of $US653,000 ($900,000) in prizemoney and the 38-year-old's world ranking dropped from 94th at the end of 2014 to now 125th.
The South Australian last won at The Barracuda Championship in   August, 2014 - a stableford-based scoring event - which was a victory to snap a four-year drought.
He flirted with retirement early last year, but with the Presidents Cup returning to Melbourne in 2019, there is now a carrot dangling in front of Ogilvy that could rejuvenate his career if he has the drive.
There are no such concerns for two-time Open winner Chalmers, who has saved his best results for domestic events in recent years.
The 42-year-old, who is now playing secondary Web.com Tour events, enjoyed a memorable summer at home when he upstaged Scott to win last year's Australian PGA Championship and finished fourth in last year's Open. The two results showed the West Australian veteran is still capable of crashing the party on his younger and more athletic competitors.
Senden, who won the 2006 Australian Open, is another player with a low profile. He will be hoping a victory in Australia can reverse the trajectory of his world ranking, which has slipped to 71st.
