Contestants
This is the ninth season of The Block to have five couples.

Team controversy
Originally in the first 48 hours of the series, there was another team, Joel Patfull & Elle Ferguson, however they left the series abruptly in the first night without notice as they found the series was not “on brand” for them, therefore the team were replaced by Rachel & Ryan. Elle posted on Instagram that reason they left was because of Joel's mother having a bad fall, but the real reason was exposed on the show. Joel and Elle were portrayed as runaways and troublemakers who put in no effort on the show, and they were generally disliked by the public.

Auction
The Auctions were held on Saturday November 5, 2022, with the episode being aired the following night. Omar & Oz broke the record for the highest amount of profit ever made in a Block auction, taking home a total profit of $1,686,666.66, which equates to $843,333 each. Meanwhile, the other auctions did not fare so well. High interest rates and inflation lead to the lowest result since 2011, with favourites Tom & Sarah-Jane taking home just $20,000.99. Rachel & Ryan passed in their home and it sold immediately after for $4,249,000.50, netting them a profit of $169,000.50. Ankur & Sharon and Dylan & Jenny followed Rachel & Ryan’s strategy by passing in their homes in hope for a better result down the track. On 11 November, Ankur & Sharon‘s house sold for $4.25 million giving them a profit of $170,000. On 13 February, Dylan and Jenny’s house was sold for an undisclosed amount more than 3 months after auction. In May 2023, it was revealed their house had sold for $3.9 million, $180,000 under reserve, meaning they did not make any profit.
