SYDNEY, April 9 (Reuters) - Australian shares rallied 0.9 percent on Tuesday, led by blue chip financials and miners after Wall Street and metals prices rose overnight.

"It's hard to say which direction the market will go but I think near term the biggest catalysts will be the results from the U.S. earnings season," said Haris Khaliqi, research analyst at Foster Stockbroking.
"There's a lot of variables at play at the moment. What's happening in Europe and Chinese trade data will also have a material impact on sentiment and direction."
The S&P/ASX 200 index climbed 43.6 points, to 4,949.1 by 0109 GMT. The benchmark rose 0.3 percent on Monday, snapping three sessions of losses.
Copper prices rose, rebounding from falls the previous week, as the euro gained ground against the dollar and a strike in Chile raised concerns over temporary supply constraints.
The mood was helped by U.S. stocks ending a volatile session higher on Monday as investors looked ahead to an earnings season expected to show modest growth despite concerns about the economy's health.
"Alcoa's better-than-expected result and stronger base metals supported early confidence," said Ric Spooner, chief market analyst at CMC Markets.
"However, economic statistics and market direction in China and Japan may set direction later in the day."

Energy and gas explorers Woodside Petroleum Ltd and Oil Search climbed 1.8 percent and 0.7 percent.
