The Government has introduced its $6.3b omnibus bill of savings measures into parliament.
That has passed the House of Representatives and is already being debated in the Senate, where it is expected to pass.
And Mr Turnbull has introduced the legislation for the Government's planned same-sex marriage plebiscite into the House, but its fate is less certain.
There was no round of media interviews to mark the first anniversary of Malcolm Turnbull coming to power, just business as usual.
The first order of the day was the omnibus budget-savings bill after the Government struck a deal with Labor to pass the changes.
The compromise deal includes an agreement to keep a clean-energy supplement for welfare recipients and to drop the planned reintroduction of the baby bonus.
Opposition Treasury spokesman Chris Bowen has reiterated Labor's support for the bill, saying it is in the national interest.
"The Labor Party worked in good faith with the Government to deliver these savings. Now, this is a good deal for the country. What we negotiated was a bigger saving than the Government was asking for, 6.3 billion instead of under 6 billion. But a fairer saving."
Mr Turnbull then introduced the Coalition's bill for a plebiscite to legalise same-sex marriage.
If it passes, he says the nation will go to the polls in February next year (2017) to vote for or against the move.
"Now, we believe that that commitment is one that all members of this parliament should support and respect. It is thoroughly democratic. It is thoroughly democratic. Every Australian will have their say. And if the Opposition supports the plebiscite in the Senate, the plebiscite can be held on the 11th of February, which is the soonest practicable date."
But Opposition Leader Bill Shorten is expected to recommend his party not support the plebiscite bill.
He will put that recommendation to the party caucus at its next meeting on October the 11th, which would lead to its defeat in the Senate and stop any plebiscite going ahead.
One year on from Mr Turnbull becoming prime minister, the Opposition and crossbenchers have missed no opportunity to take aim at him.
One Nation senator Pauline Hanson says he has achieved little and disappointed many.
"I think a lot of people have been very disappointed with him. I think they expected more of him and his performance. He's treading very -- what can I say -- thin waters* at the moment, because he hasn't got the numbers in the lower house. So the last election, I think, has been a big wake-up to the Liberal Party and the National Party, more so the Liberal Party."
Labor's Ed Husic offered advice and an unusual gift.
"Malcolm Turnbull is the man with almost everything except the one thing he really needs, and that is a backbone. And so, if I can be helpful for Malcolm Turnbull today on his first anniversary, it's to give him something he really needs in government, which is a backbone. Stand up for the things you believe in, get things done, make decisions, back them and ensure that we can get good government."
Broadcaster-turned-senator Derryn Hinch says it has not been a great year for Mr Turnbull.
But Senator Hinch says Mr Turnbull only has himself to blame.
"I've met every prime minister since (Robert) Menzies, and, the recent prime ministers, whether it be (Julia) Gillard or (Tony) Abbott or (Malcolm) Fraser, I've never seen a prime minister lose his political cachet so fast. If he had held an election last November, or even February, and gone for the usual half-senate, he would have won in a landslide, Bill Shorten would be practising his jogging, and Hinch wouldn't be in parliament."
