I was referring to paulhe's post, where, because he is Australian, he was hoping to stay more than 90 days in Spain, using the 90 day Schengen visa and 90 days allowed by a bilateral visa waiver agreement with Australia.
However that visa waiver agreement no longer seems to exist, so he is limited to 90 days stay using a Schengen visa, unless he was to apply for some other form of visa.
Those other forms of visas are talked about on the webpage you linked to - however they do of course require more conditions than a simple 90 day Schengen visa, and are harder to get.
The short-term 90 day Schengen visa simply requires that he has an Australian passport, as did the now-dead bilateral visa arrangement between Spain and Australia which would have given him an extra 90 days when that agreement existed.
