Novak Djokovic (1) def. Paolo Lorenzi
The world's top player beat Lorenzi in straight sets in their only meeting back in 2010.
Santiago Giraldo def. Matteo Viola
Giraldo is 2-11 in Grand Slams, but his only two wins have come in the first round of this event the past two years.
Tatsuma Ito def. Potito Starace
Starace is 0-6 at the Australian Open.
Radek Stepanek (29) def. Nicolas Mahut
This is a rather even match-up, but Mahut is coming off a bad loss to James Duckworth in Brisbane, so the edge goes to Stepanek.
Milos Raonic (23) def. Filippo Volandri
Raonic is one of the hottest players on tour, coming off a win in Chennai.
Philipp Petzschner def. Lukas Rosol
Someone is going to win his first career match here and the edge goes to Petzschner, who holds a victory in their only head-to-head meeting and has had more success at hard court Grand Slams.
Lleyton Hewitt def. Cedrik-Marcel Stebe
Hewitt is playing in his 16th consecutive Australian Open and while he is nearing the end of his tremendous career, the former world No. 1 is certainly capable of beating an inexperienced 21-year-old like Stebe in the first round.
Andy Roddick (15) def. Robin Haase
This is a rematch of last year's third-round contest that Roddick won in four sets.
Janko Tipsarevic (9) def. Dmitry Tursunov
This is one of the more intriguing first-round match-ups. The two split a pair of hard-court meetings last year, but Tipsarevic had the better of the play and is off to a stronger start in 2012.
James Duckworth def. Jurgen Zopp
The hometown teenager is coming off a nice win over Mahut in Brisbane.
Mikhail Youzhny def. Andrey Golubev
Youzhny has reached the third round here each of the past two years.

Gasquet is 3-1 against Seppi, including wins in each of the past two years.

Igor Kunitsyn def. Pablo Andujar
Kunitsyn took down Andujar in straight sets in their only meeting last year.
Ryan Sweeting def. Matthias Bachinger
This is Bachinger's first Aussie Open, while Sweeting reached the second round in his debut last year.
David Ferrer (5) def. Rui Machado
Ferrer reached the semis here last year.
Andy Murray (4) def. Ryan Harrison
The two-time defending runner-up is coming off a win in Brisbane.
Xavier Malisse def. Edouard Roger-Vasselin
Malisse defeated Roger-Vasselin in straight sets on the hard courts of Metz in 2010.
Ernests Gulbis def. Michael Llodra
Gulbis is 2-0 against Llodra in Tour and Grand Slam matches, beating him on the hard courts of Montreal last year.
Alex Bogomolov Jr. (32) def. Daniel Gimeno-Traver
Bogomolov hasn't played here in five years, but he's facing an opponent that is 0-3 at this event.
Viktor Troicki (19) def. Juan Carlos Ferrero
Troicki hasn't lost a first round match here since 2008, which was also the last time Ferrero won a first round match here.
Guillermo Garcia-Lopez def. Mikhail Kukushkin
Garcia-Lopez just beat Kukushkin in straight sets at Doha.
Dudi Sela def. Thomaz Bellucci
Sela overcame a two-set deficit to defeat Bellucci at last summer's U.S. Open and also beat the Brazilian in straights at the ATP Challenger Tour Finals last year.
Gael Monfils (14) def. Marinko Matosevic
Monfils has reached at least the third round here in his last four appearances.
Gilles Simon (12) def. Danai Udomchoke
Simon hasn't lost in the first round of a major since 2008.
Julien Benneteau def. Karol Beck
Beck hasn't won a match here in seven years.
Matthew Ebden def. Joao Souza
Perth resident Ebden should have the crowd behind him.
Kei Nishikori (24) def. Stephane Robert
Nishikori reached the third round here last year.
Marcel Granollers (26) def. Jesse Levine
Neither player has had much success at this event, but Granollers has the superior record on hard courts.
Ivan Dodig def. Frederico Gil
The edge goes to Dodig because he's had more success in Grand Slams.
Roberto Bautista-Agut def. Ricardo Mello
Mello hasn't won here in seven years, so it wouldn't be a shock to see the qualifier advance.
Jo-Wilfried Tsonga (6) def. Denis Istomin
Tsonga hasn't dropped a set in two meetings with Istomin.
Mardy Fish (8) def. Gilles Muller
Fish ousted Muller in straight sets at the hard court event in Los Angeles last year.
Alejandro Falla def. Fabio Fognini
Falla holds a victory in their only meeting and has a better track record here.
Albert Montanes def. Pere Riba
Montanes has become a better hard court player over the past two years.
Philipp Kohlschreiber def. Juan Monaco (25)
Kohlschreiber is 8-0 in first round matches here, and Monaco isn't exactly a hard court specialist.
Florian Mayer (20) def. Yen-Hsun Lu
Mayer beat Lu in a tight match on grass last year, and the German has the better resume at the Australian Open.
Florent Serra def. Steve Darcis
The qualifier has a good chance to move on here against a guy whose only two Aussie Open appearances were first-round exits in 2008 and '09.
Blaz Kavcic def. James Ward
Kavcic has reached the second round in three of his last six Grand Slams.
Juan Martin Del Potro (11) def. Adrian Mannarino
It's tempting to pick the upset here being that Mannarino defeated Del Potro in straight sets last year and the Argentine just lost to Marcos Baghdatis at the Sydney tune-up, but last year's match was on grass and went to two tiebreakers. In a best-of-five, Del Potro should pull it out.
Alexandr Dolgopolov (13) def. Greg Jones
Dolgopolov reached the quarters in his Aussie debut last year, and he just finished runner-up to Murray in Brisbane.
Victor Hanescu def. Tobias Kamke
Kamke is 0-3 in hard court majors, while Hanescu has at least had some success.
Sam Querrey def. Kenny De Schepper
Querrey has gone out early here the past three years, but he should end his slump against the Aussie Open rookie.
Fernando Verdasco (22) def. Bernard Tomic
Verdasco beat Tomic in straight sets on the hard courts of Brisbane three years ago.
Jurgen Melzer (31) def. Ivo Karlovic
Melzer is 5-0 against Karlovic.
Jesse Huta Galung def. Carlos Berlocq
Berlocq is 0-3 at the Australian Open.
Andreas Beck def. Eric Prodon
Prodon defeated Beck twice on clay last year, but the German is the more experienced hard court player.
Roger Federer (3) def. Alexander Kudryavtsev
The chances of a qualifier becoming the first man since 2003 to beat Federer in the first round of a Grand Slam are quite remote.
Tomas Berdych (7) def. Albert Ramos
Berdych reached the quarters last year, while Ramos is making his debut at this event.
Bjorn Phau def. Olivier Rochus
Rochus hasn’t won here in five years.
Sergiy Stakhovsky def. Illya Marchenko
Stakhovsky had a breakout year at the majors in 2011, reaching the third round of the Australian and French.
Frederik Nielsen def. Kevin Anderson (30)
It may be a match-up of qualifier versus seed, but Anderson is 0-4 at the Australian Open.
Stanislas Wawrinka (21) def. Benoit Paire
Last year’s quarterfinalist has never dropped a first round match here.
Marcos Baghdatis def. Benjamin Becker
Baghdatis is 7-0 in first round encounters at the Aussie Open.
Jeremy Chardy def. Grigor Dimitrov
Chardy beat Dimitrov in straight sets in the first round of last year’s French Open and the result shouldn’t be too much different Down Under.
Lukasz Kubot def. Nicolas Almagro (10)
Kubot overcame a two-set deficit to oust Almagro from the first round of last year’s French Open and given that clay is the 10 seed’s favorite surface, expecting a repeat on hard courts isn’t that far-fetched, especially since Kubot reached the fourth round here in 2010.
John Isner (16) def. Benjamin Mitchell
Isner has reached at least the third round here each of the past two years.
David Nalbandian def. Jarkko Nieminen
These 30-year-olds have squared off 11 times, so there is plenty of history to use in making a prediction here. Nalbandian leads the all-time series, 7-4, including victories in the past two meetings and a 2-0 record at hard court Grand Slams.
Nikolay Davydenko def. Flavio Cipolla
Davydenko beat Cipolla in straight sets on the hard courts of Montreal last year.
Feliciano Lopez (18) def. Leonardo Mayer
Lopez doesn't have the best track record here, but at least it's better than Mayer's 0-2 mark.
Ivan Ljubicic (28) def. Lukas Lacko
Ljubicic has reached the third round in consecutive Aussie Opens.
Donald Young def. Peter Gojowczyk
Young is just 1-3 at this event, but coming off a breakout Round of 16 finish at the U.S. Open, the American should be able to get past the qualifier.
Tommy Haas def. Denis Kudla
Haas hasn’t lost in the first round here since 1998.
Rafael Nadal (2) def. Alex Kuznetsov
Nadal says he feels good and that’s bad news for everyone, starting with this qualifier.
