Here's our full guide to 11 big moments coming up.
1. Toadie becomes concerned over Nell and JJ
JJ starts work at the vineyard, but is unenthusiastic over the dull tasks that Leo sets for him.
Back on Ramsay Street, Nell decides to play truant from school because she hasn't completed any of her homework assignments and doesn't want hassle from her teachers.
What to Read Next
Nell joins JJ at the vineyard and the teens get up to some mischief together. When Toadie finds out, he's annoyed that Nell seems to keep making poor choices whenever JJ is around.
2. A mystery poisoner strikes
While JJ and Nell are distracted at the vineyard, a masked figure turns up with malicious intentions.
The unknown person injects a mysterious substance into one of the bottles of wine that JJ is supposed to be looking after. This poses a threat to the imminent Eirini Rising launch, as Leo is supplying wine for the event.
3. Byron opens up to Victor
Byron's family are shocked following his heated outburst towards Victor. When Jane offers to mediate between the pair, Byron agrees to speak to his father and finally shows some support over his terminal illness.
Victor shares his plans to secure a financial legacy for Byron and Nicolette. Jane is impressed by how much her ex-husband has changed, leaving her feeling wistful over what could have been between them.
4. Victor, Byron and Nicolette spend quality time together
Victor wants to make the most of the time he has left, so he teams up with Nicolette and Byron for a game of mini-golf that he'd promised them long ago.
Aware of Nicolette's competitive nature, Victor and Byron try to keep her happy by throwing the game, but she rumbles them and encourages them to play properly.
Byron and Nicolette also agree to think seriously about a new business opportunity that Victor has offered to them.
5. Victor goes too far again
Victor gets carried away after his fun family day, as he starts meddling in Byron and Nicolette's personal lives again.
First up, Victor discovers that Nicolette has spent the night with Amira. He quickly interferes by encouraging Amira to become more serious with Nicolette.
Victor also speaks to Byron about Sadie. After hearing Byron talk about the long-term future, he shocks Wendy by revealing that Byron can see himself marrying Sadie and starting a family.
Byron and Nicolette are left appalled by Victor's tactless approach and they warn him to back off.
6. Hilary returns
Terese is surprised to learn that Hilary Robinson has bought one of the last remaining apartments at Eirini Rising. She jumps to the conclusion that Paul must have bought the apartment for his cousin.
Terese wastes no time before confronting Paul, accusing him of another scheme to remain relevant in her life. She's left sheepish when Hilary clarifies that she made the purchase without Paul knowing anything about it.
Later, Paul departs for New York following the sad news of Rosemary's death. Paul and Terese's relationship is strained once again, leaving the former couple with unfinished business.
7. Harold returns
Harold returns to Erinsborough to move into Eirini Rising. On the eve of the big launch, Terese and Toadie host a 'welcome back' dinner for the local legend.
When the grand opening ceremony gets going, Harold becomes overwhelmed by emotion and he shares how being back in Erinsborough is reminding him of his late wife Madge.
As the launch day continues, tensions continue to simmer under the surface between Terese and Susan.
Meanwhile, the threat of the poisoned wine looms large. Who will drink from the tainted bottle?
8. Karl is blackmailed over the poo scandal
Aaron's undercover work in the 'Young and Hot Males in Lycra' group pays off when he discovers that the public pooper is Jacob, a guy he'd been flirting with a few days earlier. He shares the evidence with Karl, who's thrilled over the potential opportunity to clear his name.
Sadly for Karl, everything changes when Jacob is revealed to be the grandson of wealthy Shirley Burchmore. Shirley warns Susan and Terese that she and her friends will pull out of their planned purchases at Eirini Rising if Karl exposes who the pooper really is.
9. Susan quits Eirini Rising
Eirini Rising's big launch is overshadowed by the scandal surrounding the poisoned wine. Susan and Terese find themselves divided again as they can't agree on how to handle the fallout.
Susan reaches breaking point over the difficult situation. After a heart-to-heart with Harold, she realises that she isn't happy in her new job and doesn't want to wreck her friendship with Terese, so she tells Terese to start searching for a replacement.
10. Terese and Susan try to work things out
Terese and Susan speak to their respective other halves Toadie and Karl about their ongoing Eirini Rising drama. They realise that they both take very different approaches to their work and have never set aside the time to properly address this.
This leads to an eleventh-hour reconciliation between Terese and Susan, with both agreeing to compromise and start working together more harmoniously. Can they make it work after all?

Haz is discharged from the hospital. Mackenzie prepares a happy homecoming, but is annoyed when Amira takes over.
