The 27-year-old has already filmed his first scenes as Rhys, a doctor who is tipped to cause a stir in Erinsborough as his arrival will not go down well with some of the locals.
Barber started work on set last week, shooting alongside established cast members Jackie Woodburne and Alan Fletcher (Susan and Karl Kennedy).
Speaking of his casting, the new recruit commented: "I love the character, he is very determined and focused. I'm looking forward to what's ahead."

Barber, who trained at the National Institute of Dramatic Arts, will hit screens in Australia in July.
News of his arrival follows last week's announcement that Benjamin McNair is returning to Neighbours for a four-month guest stint as Malcolm Kennedy.
Other recent cast changes have seen James Mason (Chris Pappas) and Christopher Milligan (Kyle Canning) promoted to regular fixtures in Erinsborough.
