Australian stocks have begun 2013 on a bright note, climbing more than one per cent to fresh 18-months highs as investors welcomed a deal that averted the so-called US fiscal cliff.
At 1615 AEDT on Wednesday, the benchmark S&P/ASX200 index was up 57 points, or 1.23 per cent, at 4,705.9 points, while the broader All Ordinaries index rose 58.3 points, or 1.25 per cent, at 4,722.9 points.
It was the S&P/ASX200's highest close since June 1, 2011, when the benchmark index ended the local session at 4707.3 points.
On the ASX 24, the March share price index futures contract was up 66 points at 4,682 points, with 16,488 contracts traded.
The local market, which was closed on Tuesday for New Year's Day, opened up 0.3 per cent and extended gains through the day as investors took their cues from good news from Washington regarding the US fiscal cliff.
Legislators in the US Congress and the White House had agreed on a series of measures to avoid steep tax hikes and steep spending cuts - dubbed the fiscal cliff - coming into effect at the start of 2013.
While the result was not a comprehensive solution, the US economy was tipped to have slumped back into recession and world growth knocked down - in the absence of any deal.
"Asian markets have sprung to life on the first trading day of 2013, with big gains across the risk space," IG Markets strategist Stan Shamu said in a research note.
