Big Brother: The Jenolan Caves

**Big Brother Down Under: The Jenolan Caves**, also known as **BBDU: The Jenolan Caves - Second Chances** was the fifth season of BBDU.

After 41 days, Haley won in a heavily contested 6-3 vote. Haley was widely regarded as the strongest player of the season, having won several competitions and cutting multiple threats all the while playing the middle undetected.

## Twists

### Returning Players

Sixteen former players, all of whom have played only once and did not win the game, returned for a second chance.

### Instant Immunity

Back from last season, this twist gave immunity from nominations/evictions to certain houseguests for the first four cycles of the game. However this time, the immunity would be given to the houseguest who came outright second in that respective cycle's Head of Household competition. If two or more houseguests place joint second in a HOH competition, nobody will earn immunity.

### Anonymous Week + Double Eviction

After then end of the fourth cycle, the houseguests were informed that the next cycle would be an Anonymous Week. This cycle would last for 3 days.

* DAY 1 (HoH Competition): Every houseguests would be eligible to play in the competition. The winner of this competition will become the next HoH, but they will be told that they won privately.
* DAY 2 (Anonymous Nominations + PoV Competition): The HoH will name three houseguests to be nominated, however neither the nominees nor the rest of the house will be informed about it. Then every houseguest will be eligible to play in the PoV competition along with submitting a list of every houseguest in terms of who they want to use the veto on the most, in the event that they win. The Veto will be used on the nominee who placed the highest on the PoV holder's list, and the HoH will be prompted to name a replacement nominee.
* Day 3 (Veto Ceremony + Double Eviction): The host will inform the house of the three final nominees. Everybody except for the HOH and three nominees will cast two votes to evict. The two houseguests with the most votes will be evicted.

### Hidden Boomerang Power of Veto

The Boomerang POV is a secret power of veto which gives its possessor the power to take one or both nominees off the block. The power would be rewarded by the first houseguest who solved the hidden riddles first. The power was then found by Sachi, which he never used until the power expires in the final 6 cycle.

### Viewers Vote

The viewers would have the power to cast a vote for the winner of BBDU. They voted for Haley.

In addition to that, because of Mike's ejection from the game, previous winners Manifest, Rexxy and Whoopi were brought back to form the "Winners' Council" and deliberate on the final two. They then would have to collectively cast a single vote for the winner of BBDU. They voted for Haley.
