Here are the chords to "One of Us" by Guy Sebastian.
I think that the song is really fantastic! I love the dark
mood and sound, as well as the unusual chord progression. And
as a cherry on top - to finish it off, it even has a key change! (which
really surprised me the first time I heard this song) 
As I mentioned earlier, this song has an unusual chord progression so as 
a result there are many barre chords. I've tried to simplify it as much as I 
could with my placement of the capo but some barre chords still remain. 
I don't recommend this song for beginners. Also during the key change, the chords
I tabbed out are for capo 4. However you could also move your capo up to fret 5 
and play Bm, E, G, and F instead. Have fun playing this song :)


CAPO ON FRET 4


INTRO:


Bm  G#m  Bm



VERSE 1:

 Bm
 Why is it so, that when it gets dark
     G#m
 You see so much clearer, the state of your heart
         G
 Yeah it hurts through the day, but when you're in bed
 F#
 That's when you lose, the war with your head
     Bm 
 And just when you think, you've climbed out of hell
         G#m
 All you need is a trigger, like a familiar smell
             G
 Then you're drowning in memories, you can't erase
        F#
 'Cause no one can take their place


CHORUS:

              Bm
 One of us is stronger
               G
 One of us can stay awake
                   Em
 And one of us can not send a message at 3am
          F#
 Saying I miss you babe
                Bm 
 One of us sleeps longer,
              E
 One of us is done with crying
                 G
 One of us don't feel like they die, whenever they realise
         F#
 This is not a dream
        G         F#            Bm 
 I just wish that one of us was me


VERSE 2:

   Bm 
 I don't wanna hear, about fish in the sea
        G#m
 Or that I can do better, that it's just meant to be
           G
 'Cause if there is a reason, that I can't find one
          F#
 Then I'm tired of looking, I'm tired, I'm done
     Bm
 The truth is I know, its me who's at fault
          G#m
 'Cause I took you for granted, I never gave you my all
           G
 Wish that I held you tighter, when I had the chance
     F#
 And not let you slip through my hands


CHORUS:

              Bm
 One of us is stronger
               G
 One of us can stay awake
                   Em
 And one of us can not send a message at 3am
          F#
 Saying I miss you babe
                Bm 
 One of us sleeps longer,
              E
 One of us is done with crying
                 G
 One of us don't feel like they die, whenever they realise
         F#
 This is not a dream
        G         F#            Em
 I just wish that one of us was me


BRIDGE: 

                         Bm                     Em
 They say time heals all wounds (Time heals all wounds)
                            Bm   A              G
 But clearly time ain't met you (Time ain't met you)
                           D
 'Cause if he did he would understand
        E
 That I can't live without
   F#
 I can't live without you


CHORUS:

              Bm
 One of us is stronger
               G
 One of us can stay awake
                   Em
 And one of us can not send a message at 3am
          F#
 Saying I miss you babe
                Bm 
 One of us sleeps longer,
              E
 One of us is done with crying
                 G
 One of us don't feel like they die, whenever they realise
         F#
 This is not a dream

 I just wish that one of us was me
