Chambers, 23, spent two and a half years with some success in rugby union, before signing with Super 15 franchise, the Queensland Reds.
Having had an offer from a big rugby club in Munster, it was a discussion with Frank Ponissi, the Storm’s General Manager of Football Operations, that reinvigorated Chambers desire to play NRL.
Since his departure from the Storm, Ponissi was monitoring the progress of Chambers.
â€œI have been following Willâ€™s progress over the past two years and when I caught up with him in Limmerick, it was clear he had a desire to come back to rugby league. To secure his services now is a real bonus.
â€œPleasingly we were able to agree to terms over the past couple of days, completing our 2012 roster and adding quality depth to our centre position with Dane Nielsen, Maurice Blair and Justin Oâ€™Neill,â€ Ponissi said.
â€œThis is great news for Melbourne Storm and itâ€™s tremendous to get a player of Willâ€™s calibre back playing rugby league,â€ he added.
Chambers, who was 17 when he made his Storm debut, is excited to be back at the club once more.
â€œI have thoroughly enjoyed the last couple of years, especially with Munster, who are a great club with awesome supporters,â€ said Chambers.
â€œThis was a very difficult decision with several things to consider. The overriding factor was a return to Melbourne to be coached by Craig and being part of the Melbourne Storm culture once again.â€
