Australian shares rose on Wednesday morning after a rally in commodities drove strong gains in metals and mining stocks, helping lift their index .AXMM to a two-year high.

Shanghai steel futures jumped 7 percent to their highest in nearly three weeks on Tuesday, supported by promises from China's top steelmaking province to further reduce production capacity.[IRONORE/]

Among other metals, copper hit a one-month high following further signs of a pick-up in China's economy, while zinc scaled a three-week peak on persistent supply shortages.

All of this underpinned the resource-heavy Australian market.

"The reason why the commodities or the materials sector is doing well today is because metal prices were up overnight, almost entirely across the board," says Christopher Conway, Head of Research and Trading at Australian Stock Report.

The metals and mining index .AXMM was up as much as 3.33 percent, touching its highest since September 2014.

Fortescue Metals Group (FMG) jumped 3.4 percent, while global miners Rio Tinto (RIO) surged 4 percent for its biggest intraday gain in two months and BHP Billiton (BHP) rose 3.2 percent.

Gold hit a six-week high on Tuesday, supported by earlier weakness in the dollar. [GOL/] That lifted Newcrest Mining (NCM) 1.2 percent and Resolute Mining (RSG) 3.6 percent.
