Prime Minister Malcolm Turnbull has geed up government troops ahead of the last scheduled parliamentary sitting week before the May budget.
Mr Turnbull told an "upbeat and positive" joint coalition partyroom meeting on Tuesday morning the government's top priority was having parliament approve changes to the way Australians vote for the Senate.
"It's all about democracy - the only people who benefit from these changes are the Australian voters, they will determine where their preferences go," the prime minister said.
He ruled out changes to the government's legislative agenda this week as Senate crossbenchers failed in their attempt to bring forward a vote on a bill to restore the building and construction industry watchdog.
Mr Turnbull described Labor's plan to limit tax breaks for property investors as the "the most sweeping peace-time restriction of economic freedom" that he could recall.
