I largely agree with @piecritic on this. We have made our views to DFAT known several times, and the lack of transparency hinders any meaningful criticism at this stage.
As Brendan points out, the leaks indicate that the views put forward by us (which are largely shared by intellectual property academics and activist groups with an interest in that area) have been ignored.
The submission we made on the Anti-Counterfeiting Trade Agreement (ACTA) in 2012 was, indeed, strongly worded. It was referred to numerous times within the Joint Standing Committee on Treaties (JSCOT) Report 126, and ultimately ACTA has not been ratified by Australia (nor any other country besides Japan, from memory).
We will submit to JSCOT when (or if) the TPP is finished and put forward for consideration. It has not been past practice to ignore the recommendations of JSCOT: Alexander Downer once said that ‘any government would need to think very carefully of the political consequences before it ignored a unanimous JSCOT recommendation.’
However, if a member or members are willing and able to write a submission to DFAT on the TPP, I would be more than happy to see that done. If members are interested in doing this, the authorisation process for submissions can be found here http://pirateparty.org.au/wiki/Authorisation_processes
