Even Austria did recently make two failed attempts from its current T-list, namely Hohe Tauern NP and Bregenzer Wald. I even remember reading about Steyr having feasibility studies carried out. The only Austrian T-site which is surely out is Innsbruck, but that's due to local opposition.
In 2011 the management board of the mining company decided that the plans for the nomination of Erzberg Iron Trail for WHS are stopped until an end of the mining activity is foreseeable. Since this is currently not the case, there will be no activity on our part in this issue."http://www.kleinezeitung.at/steiermark/leoben/eisenerz/2715886/welterbe-plaene-fuer-e rzberg-werden-begraben.story
Far as I remember, the problem with the nomination of the Hohe Tauern NP was, that only the part in Carinthia was certified by the IUCN, not the parts in Salzburg and Tyrol. Therefore the nomination was withdrawn. But they made up for that several years ago and now the entire NP has the IUCN certification. The Alliance of Nature in Austria sometimes points out that this issue is still pending and that it is a shame that Austria has no natural WHS, but so far with little success.
I think an inscription is justified although other alpine landscapes are already inscribed.
Innsbruck/Karwendel is interesting. Most people in Innsbruck think, that the city is well known anyways and that the WHS status would rather restrain the development of the region. And that modern architecture like the Hungerburgbahn by Zaha Hadid would not have been built with the Unesco. http://en.wikipedia.org/wiki/Hungerburgbahn
The other sites abbeys, castles, a cathedral - are on the T-list since almost 20 years. Today, these sites only have little chancec and I suppose that they will not spend the money to submit a nomination.
