Yeh in 2013 ARU stopped funding the centralized academies, from here the state unions decided to set up a u20s program which was more a representative program than an academy style that integrates players into the professional system. In 2017 the Brumbies were the first to relaunch an academy structure after they felt the time without the academy was detrimental to the player development. Lonergan and Lolesio were 2 players involved in the relaunch. The players that came through 2013-17 was arguably the lowest point in Aus rugby in terms of performance. All sides now have focused on academy structures.
Nuicifora wasn't appreciated for his work as high performance manager, he was the primary driver of Wallaby success - not Deans.
The ARU couldn't wait to see back of him, and now Ireland are the best team in the world by far, everyone cites Dean's 59% record compared to Link/Cheik, but it was really Nuicifora who drove the national team's success 2008, 2010-2012 when Australia rose to 2nd in the rankings for 4 seasons and were a pretty dominant force in world rugby.
Poor Link and Cheika were set up to fail, as there were no longer structures in place to deliver national success.
