For the first time in Block history, a contestant has quit the show.

Influencer Elle Ferguson and husband Joel Patfull have sensationally quit the show less than one week into filming.

The pair took to Instagram to cryptically mention family and it’s importance – which could explain their walk out.

Sources say that a replacement couple has already been organised and has started on site today.

UPDATE: The Daily Telegraph reports that Joel’s mum had a terrible fall and is in hospital. Joel and Elle want to be with their mum during this time. All the best to Elle and Joel and their mum – wishing her a speedy recovery.
