Very much doubt it will happen in a hurry, or probably ever.
From the July 2011 RAPAC minutes:
Nick Borley provided a brief time frame, which at best would be approximately one year. He mentioned that the process had to fit into Airservices Australia’s work schedule and had to follow the AIRAC cycle. The Chair also mentioned the concerns with regards to ownership of the IAP and the ownership of the obstacle reporting. Until this aspect with regards to allocated responsibilities has not been satisfactory addressed, Airservices Australia, who under normal circumstances would be responsible, would be reluctant to install the IAP.
