S Tier
1. 2001 - IMO the best English speaking pilot series with a great cast and great pacing
A Tier
2. 2007 - Criminally underrated with a very strong winner and some of the best weekly tasks
3. 2003 - Great concept with a loud cast, however gets a bit slow in the later weeks but has the best final 3, best winner and best finale episode
B Tier
4. 2006 - The cast was dynamic and there isn't any slow point but very gimmicky and awkward last quarter
5. 2005 - Very bogan and sexually driven cast with some stand out female housemates, the same cannot be said for a lot of the males however
6. 2004 - Notable for its controversies and final few housemates but there isn't really a majorly notable positive moment
C Tier
7. 2008 - A mess but at least its not boring
8. 2002 - Well produced just a very boring cast and dies after the week 8 double
2012 and 2013 would probably go somewhere in B tier, 2014 C tier and every single one of the channel 7 seasons is automatic F tier
