hmm... maybe i can help u out a bit here... 
after passing the CPSS, interview n medical checkup.
u will proceed to Air Force School where u await the departure date
to tamworth for Air Grading.
ur CPL rank will have to be "demoted" to OCT, which means taking
out ur physical chevron ranks on ur no 4 n putting on the OCT
epaulette.
Air Grading in Tamworth is roughly 1 mth plus minus a bit.
if u pass Air Grading, u will then proceed to OCS for future
training as a 2 white bar OCT. training will also include jungle
survival training in Brunei.
after ur OCS training, u will be back to Air Force School for
further ground sch as a 3 bar OCT. once u finish ur ground sch, u
will be heading to Pearce for Basic Wing Course of abt 1 yr or
so.
total training right from the moment u step into Air Force School
is about 2 years. n yes... u will be OCT for 2 yrs... 
even the RP at AFS will try to pull rank on u cos u r OCT....
gd luck~!
