[2] Nathan Little was the first housemate in the Big Brother franchise worldwide to evict himself and give his spot to another player.
[3] Dormer later won a public vote to compete in the fourth season of Big Brother Canada.
The renewal of Big Brother was predicted before the finale of the previous season due to the success the reboot had in ratings.
[6] On 21 July 2013, after the housemates had entered lockdown, it was confirmed that a weekly live games task would take place in the first four weeks of the season; it was known as the 'Saturday Showdown' and was hosted by Shelley Craft, with commentary from Mike Goldman and 2012 housemate Michael Beveridge (although the 'Saturday Showdown' was later revealed on the official website to be a pre-recorded showing of the previous night when the games took place and that no live recording would be done).
On 25 July 2013, speculations surfaced on whether the eviction shows would be moving to Monday nights due to the returning of Australia's Got Talent.
[11] On 24 October 2013, it was announced that Big Brother Australia would be returning to New Zealand on TV3,[12] after a seven-year absence following the conclusion of the 2005 series.
Showdown was no longer hosted by Shelley Craft, and Michael Beveridge no longer provided commentary as the games were now shown in sequence during the daily show depicting Wednesday's events – with Mike Goldman, the sole survivor of the revamp, who provided the narration as per normal.
[13] At the same time, it was also announced that beginning on 27 August 2013, Nine would air a new show titled Late Night Feast at 9:30PM once a week.
Each episode depicted the events that took place during a party thrown by Big Brother days earlier on Friday night.
While the housemates sat at a table eating food and drink provided by Big Brother, they discussed topics aimed more towards adult viewing – including religion, sexuality and politics – and then proceeded to play party games and were then given music to dance to.
[14] Unlike other adult-orientated shows that had previously aired on Ten – UpLate, Uncut and Adults Only – the show was not hosted, nor did Mike Goldman provide any narration – instead footage of housemates in the diary room on the Saturday, discussing the previous night's events, was shown to link the various segments together.
[18] Ultimately this proved to be a cancellation of the entire Confidential format, as unlike its early end the previous year, it did not return for the subsequent series.
Originally planned to end on 23 October 2013, rumours began circulating in late September 2013 that the series had been extended by two weeks.
This was fuelled by the previous year's winner, Benjamin Norris, mentioning an extension in a blog post on 17 September 2013 that covered that week's fake double eviction.
On 26 September 2013, tickets appeared on the Dreamworld website to an Eviction show that would take place on the original finale date, thus confirming that the series had been extended in some capacity.
[48] On Day 2, Sonia Kruger hosted a special live show that saw the second part of the season's twist revealed as Drew and Jade entered the Safe House pretending to be a married couple.
On Day 58, Sonia Kruger hosted a special live show that saw two intruders enter the house, Nathan and Justynn.. On Day 64, Sonia Kruger hosted a special live show that saw two female intruders enter the Big Brother house.
On Day 95, Sonia Kruger hosted a special live Halloween show that saw the remaining five housemates, Boog, Drew, Jade, Tahan and Tim to view 'trick' and 'treat' packages.
