It's shaping as The Hangover: Canberra for partying politicians and their staff.
Parliament House cleaners will add a sour note to the busiest week of boozing before the long summer recess by calling a strike for next week, refusing to clean up after MPs and senators for up to five straight days.
The final sitting week in Canberra is the biggest for Parliament's 40 full-time cleaners, with the added burden of thousands of empty bottles from Christmas drinks functions and impromptu gatherings in offices up and down the corridors.
Opposition Leader Bill Shorten will kick off celebrations with drinks with the press gallery on Tuesday.
On Wednesday, United Voice, the union representing the cleaners, alerted Limro Cleaning Services, the company contracted to the Department of Parliamentary Services, that an initial 24-hour stoppage would begin on Monday.
The union must continue making alerts to facilitate a full week of strike action.
The wages of cleaners have been frozen at 2012 levels - $21.10 an hour - after the Commonwealth cleaning services guidelines were scrapped by the Abbott government.
They want an extra $1.80 an hour to reflect what they would have been being paid had the guidelines remained in place.
ACT branch secretary of United Voice Lyndal Ryan said she hoped Prime Minister Malcolm Turnbull would reconsider and that "party time" in Canberra was a good opportunity to remind the government how essential cleaners are to the operation of Parliament House.
"It's not the cleaners who drink. They want to put pegs on their noses with the stench of all the stale alcohol in the last week," she said.
It was cleaners who had to deal with the aftermath of a wild party in the prime ministerial suite on the night Tony Abbott was rolled by Mr Turnbull.
According to emails aired at a Senate hearing in October, cleaners discovered a smashed marble table in the prime minister's suite, reportedly smashed after a heavy person or persons had danced on it.
Pieces of the table, bought in the 1980s for $590, were seen in the offices of certain Abbott loyalists on the same morning, having apparently been souvenired on the night.
Mr Abbott later agreed to pay for the damaged table.
Limro Cleaning owner Bob Trpeski was "out of town" and unavailable for comment, according to staff.
