Viewers down under will see Paulie arrive in Summer Bay later this week, much to the surprise of his older brother Angelo (Luke Jacobz).
It soon becomes clear that there's an agenda behind Paulie's sudden appearance and he wants Angelo's help - but, with bad blood between the brothers, will he get what he's looking for?
Paulie is played by actor Ryan Johnson, who should be a familiar face for fans of Australian TV, as he's previously starred in The Secret Life Of Us, Underbelly and Out of the Blue among other shows.

Speaking to TV Week about his new role recently, Ryan teased: "Paulie has always been the starry-eyed dreamer in the family, and his desire to think big has landed him in a lot of trouble. He acts before he thinks. Even when they were kids, Paulie's done crazy things and Angelo has had to bail him out."
He added: "[Paulie's] arrival is a complete surprise to Angelo. Angelo's taken the rap for his brother's mistakes many times and knows Paulie wouldn't just show up if things were going well. If Paulie's in town, there has to be some sort of agenda. Angelo's waiting for the truth to come out."
There will have been some familiar faces on set for Ryan on his first day of filming as Samara Weaving (Indigo Walker) and Shane Withington (John Palmer) were also cast members on Out of the Blue.
Home and Away returns to Five on September 6.
