World golf's "generation next" will have Jordan Spieth in their sights at this year's Australian Open.
More than any other Open in recent memory, the "amateur factor" is set to play a big part at the 100th edition of the summer's flagship event, with three of the globe's top 15 ranked amateurs confirmed to take on the Australian Golf Club next month. 
American young guns Bryson DeChambeau (world No.6 amateur) and Jordan Niebrugge (world No.14) as well as Australia's own wonder-kid Ryan Ruffels (world No.8), will join Golf Australia squad star Brett Coletta in attempting to become the first amateur to win the Australian Open since Aaron Baddeley in 1999.
While Ruffels is becoming better known to Australian audiences, DeChambeau looms as the one to watch given his amateur record has already put him alongside golfing royalty and there are big expectations surrounding his future.
The 22-year-old is one of only five players to win both the US Amateur Championship and the NCAA Division I Championship in the same year - a feat he accomplished in 2015 to join legendary company including Jack Nicklaus (1961), Tiger Woods (1996) and Phil Mickelson (1990).
DeChambeau could provide one of the most interesting storylines of the tournament, with the combination of his unconventional swing and custom-made clubs - he has used irons and wedges with the same "7-iron" length or "37.5 inches" - his fashion sense, often wearing an old-school "tweed" golf cap,  and his personality. His major at college was physics and he approached the game with the mind of a scientist.
The number of amateurs to enter the Australian Open field is yet to be finalised.
The impact of amateurs at this year's event would have been even bigger had another Australian talent, Cameron Davis (world ranked No.36), not been forced to withdraw from the summer's events because of wrist surgery.
With younger stars such as Spieth, Rory McIlroy and Jason Day taking over the sport at the highest level, the world's best amateur players are also being viewed in a different light - and in some cases as legitimate contenders in certain tournaments and there was recent evidence of that at the Australian Open.
It was at the 2013 Open that Ruffels first announced himself  by becoming the youngest player  to make the cut and eventually he finished inside the top 25 in the race for the title won by McIlroy.
Then, last year Victoria's Lucas Herbert also achieved a top-25 finish, to go with a tie 11th at the Australian Masters the week before.
The rise of the amateurs has also been felt on the international stage, and no more prominently than at this year's British Open.
Irish amateur Paul Dunne was a joint leader after three rounds at St Andrews, while Niebrugge was the leading amateur in the field, finishing equal sixth - just three shots behind Spieth and Day, who tied for fourth.
Another amateur, American Brian Campbell, was also tied for fourth after the first round of this year's US Open, which was won by Spieth.
