The ensemble cast including Brooke Satchwell, Michael Dorman, Peter Phelps and Tracy Mann will return before the cameras in Sydney in late March.
The renewal for the series about four young Australian couples is in addition to 9 remaining episodes from Season One which are yet to play out.
The Fremantle-produced drama which premiered last year received mostly positive reviews while a TEN statement says it ranked number one in its timeslot for people aged 25 to 54.
TEN Head of Drama, Rick Maier, said: “All power to the cast and crew who delivered such a fun show for us last year. We are looking forward to more stories of love, lust and intrigue from the busiest and most romantic block of flats in the country.”
Jo Porter, Director of Drama at FremantleMedia Australia, said: “We will be building on the strengths of the warmth, romance and humour of our Wonderland residents. In season two viewers will share unexpected twists and turns, fast-paced storylines and dramatic cliff hangers that will test all our characters.
“We are looking forward to viewers getting to know Australia’s favourite flatmates even better as they face love affairs, break-ups and revelations of deep secrets within the Wonderland building. We all can’t wait to get started.
TEN’s local drama slate for 2014 already includes Offspring, Puberty Blues, Secrets and Lies, Party Tricks and, on ELEVEN, Neighbours.
