The group flies to Sydney for Pete and Jo's wedding. David books a hotel room with a view of the harbour in an effort to make a new start with Karen. Impressed by this, she emails Mark to tell him that the affair is over. Rachel meets with her sister Lucy (Susannah Doyle), who tells her she is screening men to father a child with, despite being a lesbian. Adam volunteers his banked sperm but Rachel talks him out of it. Pete meets Jo's rich father, Rod Ellison (Gary Sweet), who tries to pay him off after thinking he is marrying Jo only for the money. Pete flatly refuses. Mark arrives in Sydney, telling Karen he has left Geraldine to be with her. When David tells Karen that he wants the family to move to Australia, Mark reveals the affair, leading to a fight between the two. Adam changes Rod's mind about Pete and the couple prepares to marry. Rachel goes into premature labour and is given a caesarean section at the hospital. At the wedding, Pete is without a best man and the rings, so David and Karen offer theirs. Karen tries to talk to David after the ceremony, but he refuses and flies back to England alone.

Pete and Jo return from Australia. Their honeymoon is soon over when Pete's mum comes to live with them and Jo is forced to live with the memory of Jenny. A rift develops between Adam and Rachel.

Pete and Jo are interviewed by the Immigration Department to confirm the legitimacy of their marriage. All goes well in the end but Pete starts to doubt Jo's real reason for getting married. Adam is made redundant so Rachel goes back to work.
