Just having a look at YT analytics and discovered that Spanish BigBbrother 16 (Hermano Gran 16)starts in two days and there is commentary that their "Secrets" promotion has been "copied" from BBAU9:
GoogleTranslate(d) :
'Big Brother 16', an edition of secrets ... arrived from Australia?

Telecinco has copied a promo point by point to the ninth edition of Big Brother in Australia used to announce one of the most important developments of that year. Secrets.
