I'm still surprised that many posters here continue by implication to impute to RA a rational, objective, considered approach to the matter of selecting the elite coaching resources to manage the Wallabies.
Going right back to: the crazy multi-year extension of Deans' contract well pre RWC 2011, the post RWC 2011 ARU imposition of ACs on Deans and that did not work well, the debacle of Link's departure, the non-examination and non-change of any ACs as 2016's Wallaby results showed serious problems or deficiencies within the coaching group, Cheika's and RA's endorsement of Larkham as 'the anointed successor' to Cheika based upon zero evidence that Larkham was even a good national AC let alone ready to be HC, the ARU appointment of Kafer to head 'national coaching strategy' with zero relevant track record or experience to do such a crucial job, the poor state of Aust elite coaching resources at Super level .....we could go on.
The point being that there is no positive and compelling evidence of any kind that the modern ARU/RA genuinely understands the processes necessary to recruit, identify, build, develop Australia's national elite rugby coaching resources. None.
Systemic problems of managerial capability do not spontaneously cure themselves. They are only cured by radical managerial change of the appropriate kind.
Accordingly the statistical likelihood that RA will get late 2018 changes to the national Wallaby coaching set-up right either tactically or strategically is about 1 in 50.
