Whilst six-foot tall men often roam the halls at Geelong Football Club, they don't usually spend their days underwater.

On Tuesday however, The Cattery played host to a group of such men, as members of the Royal Australian Navy stopped by whilst they were in town.

Five Navy officers were welcomed into Geelong Football Club, with Vice President Bob Gartland giving the group a tour of Simonds Stadium and the Cats facilities.

It comes after locals were shocked to spot a submarine in Corio Bay at the weekend with, what was later confirmed as the Collins class sub HMAS Rankin, turning up unannounced.

The Royal Australian Navy has kept the submarine's reason for being in Geelong under wraps.
