By Adwitiya Srivastava Nov 9 (Reuters) - Australian shares finished at a three-week high on Thursday led by mining and financial stocks, while investors awaited U.S. jobless claims data and a speech by the Federal Reserve chair. "With monetary policy restrictive, we expect the easing trends in inflation and hiring will continue and thus believe the Fed has finished raising rates in this tightening cycle." However, the National Australia Bank NAB.AX fell 0.8%, erasing earlier gains, as the country's top business lender's annual cash profit missed analyst estimates.
