By Riya Sharma Oct 1 (Reuters) - Australian shares ended lower on Friday, dragged down by major banks and heavyweight miners, as a slew of weak economic data from China and growing global inflation concerns doused risk appetite. "Concerns are looming over China's economic slowdown with the country flagging that it's in no hurry push up stimulus and suggesting bailing out the locals while leaving offshore investors out in the cold." Miners .AXMM dropped 1.9% as prices of copper, aluminium and nickel fell on a firmer U.S. dollar.
