Hey Roy..... I was a Official last year in a Course Car, unfortunatly i took my time sorting stuff out this year and wont be one........ BUT this means i will be going to watch it from various points! and as a bonus i have the pace notes and maps of all four days! Very Handy!
If your looking for great spots to watch from, there are HEAPS, just gotta know when they start coming thru and and when the roads close off.
I assume you have been to thier website??

But be sure to go to the Street Party on Friday night in the city on Gouger St......... Cars all line up for viewing and a crap load of people, with a crap load of cafes!
Oh yeh and the Prologue on Wednesday i believe........ they use part of the F1/Clipsal track, well thats if your here then!
