Australian shares advanced 1.2 percent on Monday but finished off their highs as investors focused on the hurdles ahead for Europe after a eurozone summit, and some softer Chinese import and Australian export data.

The index dropped 1.8 percent on Friday to a two-week low. New Zealand's benchmark NZX 50 index gained 0.9 percent to 3,299.
Shares in Aston Resources jumped as much as 5 percent after it agreed to merge with Whitehaven Coal to create a A$5.1 billion coal miner. Aston shares finished up 1.4 percent to A$9.90, just below the merger valuation, while Whitehaven fell 1.4 percent. Origin Energy shares climbed 3 percent after its joint venture partner Sinopec agreed to increase its stake in the Australia Pacific LNG project to 25 percent.
Other energy stocks benefited from Origin's gains, including Santos up 3.2 percent and Woodside Petroleum up 1.5 percent. Qantas shares underperformed the market, falling 0.3 percent, after the airline tried to reassure investors that domestic bookings have recovered back to normal levels after months of industrial disputes and said it was still talking about setting up a premium airline in Southeast Asia.
