A tense new promo, which can be viewed at the top of the page, has teased a huge shock for killer Colby Thorne (Tim Franklin) as he finally discovers which of his allies has betrayed him.

Recent episodes on air in Australia have seen Colby get charged with the murder of Ross Nixon after someone came forward to give detective Angelo Rosetta a witness statement.

The show has now confirmed that Willow Harris (Sarah Roberts) is the person who has turned against Colby, in a bombshell storyline twist.

Home and Away's new promo, teasing scenes due to air next week in Australia and in early 2021 in the UK, shows Colby left shellshocked when the truth comes to light at his trial.

Colby can't believe what's happening when Willow is called to give evidence against him in court. Could her testimony ultimately send Colby away to prison, crushing his sister Bella Nixon and best friend Dean Thompson?

Willow's involvement comes as a major shock, as she has known about Colby's guilt since last year and loyally protected his dark secret.


Over time, however, Willow has grown concerned over Colby's attitude towards the cover-up as his actions have started to adversely affect those around him. It seems this was the final straw, prompting her to switch sides.

Home and Away is airing new episodes on Channel 5 until Friday, November 20, when the show takes its annual winter break on UK screens.

Scheduling details for Australia's season finale on Channel 7 have yet to be confirmed.
