Has the government learned its lesson as one year anniversary of Turnbull's coup looms

Has the government learned its lesson as one year anniversary of Turnbull's coup looms

One thing is certain about the second week of the new parliament - no MPs will be taking an early mark.

The debacle of the previous sitting week's end was a lesson that will ring loud in the ears of the coalition.

Coalition MPs will be hauled in front of Leader of the House Christopher Pyne on Monday morning for a reminder the government's one-seat majority means everyone, including the prime minister, needs to be within four minutes of the chamber for votes.

Malcolm Turnbull will be hoping to forget the embarrassing display when his slim majority and the carelessness of several MPs already at the airport cost his government a series of votes.

Instead, he'll hope his achievements take centre stage as he marks one year since toppling Tony Abbott.

Mr Turnbull claims a long list, including "jobs and growth", a clear economic plan, an innovation agenda and a defence industry plan.

"So far, so good," he said when asked about his first year in the top job.

But others might not be so complimentary.

Opposition Leader Bill Shorten characterised the past year as one of "disappointment, dithering and disunity".

"A lot of Liberals are thinking 'why did we bother?' and a lot of Australians are thinking 'what was the point?'" he told AAP.

Mr Shorten is also trying to put an embarrassing saga behind him after his frontbencher Sam Dastyari stepped down for asking a Chinese donor to pay a personal travel debt.

But the saga's remnant push to ban foreign donations will linger as Labor, the Greens and independents call on the government to support reform.

The government wants the focus to be on its $6 billion budget savings bill - a compilation of measures Labor has indicated it will support.

Finance Minister Mathias Cormann says it should fly through parliament.

But Labor has flagged it may no longer support ripping carbon tax compensation from new welfare recipients - a measure saving $1.3 billion.

The government will also introduce two new counter-terrorism laws, setting up post-sentencing indefinite detention of convicted terrorists who authorities believe may re-offend.

But its preferred points of focus face derailment with three same-sex marriage bills to be introduced or debated.

Mr Shorten's bill to allow gay marriage is expected to be introduced on Monday, followed by a crossbench attempt - but neither will be debated right away.

Cabinet and the coalition partyroom are expected to finalise details of the plebiscite on same-sex marriage early in the week.

Plus a Greens bill will come up in the Senate on Thursday, and 48 parents and children will lobby against government plans to hold a national vote.
