Watney has won twice on the PGA Tour this year and plays the Emirates Australian Open for the first time.
"I'm really looking forward to being a part of the Championship in Sydney," Watney said. "Most of my family are coming down for it".
"There seems to be a real buzz around this year's Open leading into the Presidents Cup and it is amazing how many top international players have won the tournament" he added.
Kuchar will play the Emirates Australian Open for the second time since his debut in 2000 at Kingston Heath Golf Club.
A holder of three PGA Tour titles, Kuchar has had another exceptional year on the PGA Tour including ten Top 10 finishes and twice runner-up.

Kuchar, Watney, Allenby, Mahan and Senden join Tiger Woods, Dustin Johnson, Adam Scott, Jason Day, Bubba Watson, Greg Norman, Fred Couples and defending champion Geoff Ogilvy in one of the best fields in years.
Golf Australia CEO Stephen Pitt said the anticipation for the Emirates Australian Open was building rapidly.
"The excitement around the Open is extraordinary and we want to make sure no one misses out. Get in and buy your tickets now so you can come straight in and get into the thick of the action.," Pitt said.
"Having players of the calibre of Matt Kuchar, Nick Watney, Hunter Mahan, Robert Allenby and John Senden to Sydney only add to an already spectacular field. The countdown to the Open is well and truly on."
