Smith, who played last week's Memorial Tournament where he played on invite, gave further evidence as to why he is considered such a promising talent by recording rounds of 69 and 67 to secure one of the 15 spots available from his venue.
This will be Smith's first major championship and continues an impressive start to his professional career which included being rookie of the year on the Asian Tour last year.
The former Australian Amateur Champion has made the cut in three of the last four PGA Tour events he has played in 2015 including 15th place finish at Hilton Head.
His access to PGA Tour event invites has come largely as a result of a great 5th place finish at the CIMB Classic in Malaysia last year, opening up opportunities in the US. He has all but used up the invites available to him in any one season but his effort this morning creates another chance to gain experience and perhaps something considerably better.
The unlucky Australian was Rod Pampling who appeared in control of a place in the field after his morning round at his qualifier in Dallas but a double bogey at his final hole of the afternoon round would see him miss by one.
Tasmanian Clint Rice missed out by one shot on what would have been a surprise result at his qualifier in Ohio.
So democratic is the qualifying process that even two time US Open Champions Retief Goosen and Lee Janzen were forced to go through the process with both playing their way into the field.
Former world number one Luke Donald was another to qualify when he tied for first at his venue in Florida.
Also teeing it up was last week's Memorial winner David Lingmerth who despite his huge victory on Sunday will not tee it up at Chambers Bay.
