(Updates to close)
SYDNEY, Aug 11 (Reuters) - Australian shares fell 0.7 percent on Tuesday, largely led by losses in banks, after China devalued its currency following disappointing economic data.
Healthcare stocks also fell after weaker-than-expected earnings guidance from Cochlear Ltd COH.AX.
China's central bank sharply weakened the yuan on Tuesday, saying it had changed the way it calculated the currency's daily midpoint against the dollar. China is Australia's No.1 trading partner.
The S&P/ASX 200 index .AXJO fell about 36 points to 5,473.2 points at the close of trade. The benchmark gained 0.6 percent on Monday.
Cochlear, the world's top hearing implants maker, missed expectations to post a 56 percent gain in annual profit, cut its full-year dividend by 25 percent and forecast slower-than-expected profit growth in 2015/16, sending jitters through investors in the health sector.
New Zealand's benchmark NZX 50 index .NZ50 fell 0.73 percent or 42.67 points to finish the session at 5,822.35.
