It comes in the wake of the saga surrounding Health Minister Sussan Ley.
The government says it wants to clean up the system, but there are calls forn an independent watchdog to be introduced.
Fearing a major backlash from voters, reform of the entitlement system has fast become a top priority for the federal government in 2017.
An inquiry after the expenses scandal that cost Bronwyn Bishop the job of Speaker of the House of Representatives was completed last year.
It found the parliamentary expenses is complex, confusing, and contradictory.
It's recommended, amongst other things, creating an online system to publish expense details monthly, better defining the term "parliamentary business", and tightening eligibility for business class trips for politicians' family members.
Acting Special Minister of State Kelly O'Dwyer says this federal government is finally acting where previous gvoernments didn't.
"The parliamentary expense system needs to change. Theer are many governments before that have ducked this issue. The Turnbull government is dealing with it."
Overall, the report has made 36 recommendations.
Ms O'Dwyer says the government accepts all those recommendations, and is dealing with the issue by working to implement them.
"The government needs to streamline the current system for parliamentarian work expenses. There has already been an independent review into workplace expenses. The government has accepted, in principle, all 36 of those recommendations. And the government is already working on the implementation of those recommendations."
But that hasn't stopped discussion of the issue, by other politicians, or the public, as new details emerge of certain expenses claims.
It's been revealed that, nine months before Sussan Ley made her impulse purchase of a Gold Coast apartment whilst on a taxpayer-funded trip there, she reportedly made an unsuccessful bid for another Gold Coast property on another publically-funded visit.
And the Education Minister has moved to defend himself against reports he made indefensible claims.
Simon Birmingham now says he only claimed a taxi fare in Sydney on December 31st, 2015, and that was for a work meeting.
Several government ministers reportedly claimed flights, car costs, travel allowance, or all three, to attend an event hosted by the Prime Minister at Kirribilli House in Sydney on that New Year's Eve.
Greens Leader, Senator Richard Di Natale, has told Channel Nine that likely cannot be justified.
"It's hard to see that a New Year's Eve function could be parliamentary work. There are politicians who want to exploit the system, and they're dragging their heels, so that they continue to get everything they can out of it."
Politicians from across the spectrum are admitting that these latest episodes expose flaws in their profession.
Indepedent MP Andrew Wilkie says the present rules aren't strong enough.
"Parliamentarians are surrounded by a very weak regulatory framewrok when it comes to the expenditure of allowances, and that allows wrongdoing by some MPs."
And many are aware of how such scandals affect how all politicians are perceived by the public.
Senator Nick Xenophon has told the ABC situations like Ms Ley's one contribute to people disliking the elected representatives.
"This is why so many Australians hate so many politcians- because they don't seem to be subject to what is commonly known as the pub test."
Labor MP Linda Burney says Ms Ley's use of taxpayer funds- and what she was doing on the Gold Coast once she'd travelled there with those funds- buying an expensive property- reinforces the opinion some people have of politicians as being selfish.
"Who on earth has a spare eight hundred thousand dollars to buy an investment property on a whim? You need prior bank approval, you need a whole range of things cleared before you can make that offer at an auction. I think Sussan Ley has unfortunately fed into the view held by many Australians that polticians are in it for themselves."
Some politicians have used the situation to advertise their own thrift with taxpayer money, as well as proposing punishment for transgressors.
Senator Pauline Hanson says fines should apply for those who rort the system.
"Whenever I travel, I only book economy air flights, because I'm looking after the taxpayers. If politicians do the wrong thing by the public, they should be heavily fined over it, There has to be accountability."
Some have even suggested a federal Independent Commission Against Corruption, much like that of New South Wales, be set up to deal with this kind of behaviour.
The government is promising major change within the first half of this year.
As for Sussan Ley, her fate will be sealed much sooner.
The investigations into her travel and expenses will likely be completed by the end of this week.
