When Natalie suggests having another baby, Joel agrees, and after the family vote on the subject, Tom supports them. However, when they fail to conceive, Natalie suggests they have tests and Joel learns he has a low sperm count, making it unlikely he will have more children. Joel and Natalie then focus on the children they have by hiring Robert Perez (Tony Poli) as a tutor for Gypsy, with Joel unaware that he is actually an old acquaintance, David D'Angelo. It emerges Joel had arrested David in Hong Kong years ago, and he takes revenge on the family by kidnapping Natalie and Gypsy, then burning the family home to the ground. David is then arrested and jailed. Left homeless, the family move in with Travis and his wife Rebecca (Belinda Emmett) at the caravan park. They try to buy a new house, but are devastated to learn David has cleaned out the account after impersonating Joel. The stress gets to Joel when he lashes out at a Heckler at one of Tom's cricket matches and nearly lashes out at Tom later. Worse is to come when he is accused of breaking a thief's arm and consequently suspended, but the enquiry reveals the boy's injuries are inconsistent and Joel is cleared. More family dramas ensue when Travis tracks down a woman named Claire Andrews (Kate Beaham), who is revealed to be their half-sister, a result of an affair Jack had. Claire steals from Travis, and Joel insists on having her charged, but Travis decides not to.
