Dark Angel DVDs - where are the commentaries?

[Warrior 4 Jesus]

I have seasons one and two on dvd (legit ofcourse) but they are Region 4. The don't seem to have commentaries on them like the Region 1 counterparts do.
Just wondering if anyone knows where I can find transcripts of the commentaries.

And I'll just vent that Australia once again gets screwed over in the Special Features on DVDs department.
