TOPSHOTS A shadow of a girl casts on the ground as people head to their work in the central business district of Sydney on March 7, 2013. Australia's economy grew 0.6 percent in the three months to December thanks to a pick-up in exports but analysts warned the country's mining boom covered up weakness in other sectors. The bureau of statistics said the quarter-on-quarter expansion followed a 0.7 percent gain in the September quarter, and resulted in a 3.1 percent annual growth rate in 2012, compared to 2.3 percent in 2011.
