Open house BBAU
 

Apparently, acording to wikipedia, the BBAU house is open to the public after the series has ended. Is this true?

Yes it is. Every year, the house is available to the public but they can't go everywhere they want to. They follow a way.

Its like an attraction seem as how its in DreamWorld a theme park!

You follow a line through the house

In fact, if you pay a certain fee, you can hire the Big Brother house for parties and stuff. I live about 15 mins from where the BB house is and I know a few people that have been to parties there.
