Prime Minister Tony Abbott is ducking earlier threats to take Australians back to the polls as Labor and the Greens dare him to call an early election.
Abbott now has the trigger within reach for a double-dissolution election, following the second rejection by the Senate of his efforts to axe the profit-earning corporation set up by Labor to finance renewable energy projects.
The Clean Energy Finance Corporation is one of a package of climate change and environmental programmes the Government wants to dump, promoting instead its own "direct action" policy to reduce greenhouse gas emissions.
Faced with a list of potential roadblocks in the Upper House, Abbott had previously hinted heavily of a new election in which the entire Senate would be up for grabs, instead of just the half normally contested.
Governments are given the option when legislation is rejected twice in the Senate within three months.
