Here are some of the significant items from the full list of stalled and struggling bills, worth some $10 billion in savings over four years. Crossbench senators David Leyonhjelm, Zhenya "Dio" Wang, Ricky Muir, John Madigan, Bob Day and Glenn Lazarus. University deregulation and funding cut One of the Coalition's most controversial policies remains on the table - officially. The changes, including a $1.9 billion cut to higher education funding, were voted down twice by the Senate and the sector is demanding certainty on the future of the legislation. Abolition of the Clean Energy Finance Corporation and climate changes bodies

The government's two failed attempts to abolish the CEFC, a body that provides loans for clean energy projects, form one of its double dissolution triggers. It was reported that the Turnbull government has quietly shelved the plans but it remains official policy, as with related bodies the Australian Renewable Energy Agency and the Climate Change Authority. Senate crossbenchers and Greens have joined Labor to halt much of the Coalition's legislative agenda.

Worth $674 million over four years, Labor now refuses to support the cuts on the basis that government is not fully funding the secondary school funding changes. Childcare package and family tax benefit cuts

A $3 billion childcare package was at the centre of the 2015 budget but has seen little activity as changes to family tax benefits - which the government insists are needed to fund the package - fail to attract support in the Senate. The family tax changes would see certain parents have their payments cut and save $4.8 billion over four years. Limiting "double dipping" in paid parental leave In December, the government modified reforms to paid parental leave for 80,000 new mothers after the opposition and Senate crossbenchers refused to support them. The new changes would deduct weeks of employer-provided paid leave from the government's 18-week scheme but face likely defeat in Parliament. Charging interest on university loans The 2014 university changes package included charging real interest - up to 6 per cent - HELP loans, previously pegged to rises in the cost of living. The change would be worth $313 million over four years but has died in the Senate.

Australian Building and Construction Commission The government's attempt to re-establish the ABCC watchdog could be used as a double-dissolution trigger if it is introduced to the Senate again. Established by the Howard government and abolished by Labor, the Coalition says it is key to tackling the kind of union corruption revealed in the trade union royal commission. Another union oversight body A bill to establish a body overseeing and investigating unions has failed twice in the Senate and Employment Minister Michaelia Cash has said it could be justifiably used as a trigger for a double dissolution. Crackdown on environmental "lawfare"

The Coalition has sought to limit the ability of green groups to hold up mining projects with legal action. The government has argued the actions can sabotage the investments of companies while opponents see them as anti-democratic and restrict the right to uphold environmental laws. The changes face likely defeat in the Senate. Wait for the dole A one-month wait for unemployment payments - a compromised version of the original six month wait proposed in the 2014 budget - ran into a wall in the Senate, costing the government $173 million in savings. Both versions were heavily criticised by the opposition and crossbenchers. Follow us on Twitter
