BARNABY JOYCE
Joyce is the under-fire leader who has taken leave following revelations of his affair with former staffer Vikki Campion, who is now pregnant with his child.
The MP, who was first elected to the Senate in 2004, insists he isn't for moving, labelling calls to oust him a "witch-hunt".
It's been a big six months for Joyce, who was found by the High Court in October to be a New Zealander and had to contest a by-election in his seat of New England.
BRIDGET MCKENZIE
The senator who became Joyce's deputy in December is sticking by her leader, offering a "rolled gold guarantee" he will remain in the position.
The new sports minister is also away while Joyce is on leave, representing the government at the Winter Olympics.
DAVID LITTLEPROUD
Littleproud, a first-term MP, has enjoyed a meteoric rise in the Turnbull government, being appointed agriculture minister at Joyce's insistence in December.
He has urged those agitating against the leader to "put up or shut up".
NIGEL SCULLION
The Northern Territory senator, who was named interim parliamentary leader when Joyce was contesting the by-election, has backed the leader to remain.
In an outburst to reporters, Scullion labelled reports about Joyce's affair the biggest beat-up he's seen.
MATTHEW CANAVAN
The former chief-of-staff to Joyce, Canavan was also caught up in the revelations after he employed Ms Campion.
The resources minister won his own High Court fight last year over his Italian citizenship.
MICHAEL MCCORMACK
In a car-crash television interview, the NSW Nationals MP refused six times to support Joyce as leader, relying on the phrase "at the moment".
The man seen as the most likely contender to replace him finally said "of course" he supported Joyce.
DARREN CHESTER
The former infrastructure minister was dumped in the December reshuffle, losing his portfolio to Joyce.
The action against the Victorian MP was seen by some as a rebuke from Joyce against Chester.
KEITH PITT
The now-backbencher from Queensland was also dumped from his trade responsibilities in the reshuffle and has been laying low since the Joyce reports surfaced.
GEORGE CHRISTENSEN
The outspoken MP and former party whip has backed his leader and says he continues to have the support of the party room.
But Christensen has labelled Malcolm Turnbull's new ban on ministers having sex with staff as "bonkers".
DAMIAN DRUM
Drum has also slotted in behind his leader and insists he understood Joyce's affair with Ms Campion was over when she moved to work in his office.
BARRY O'SULLIVAN
The outspoken Queenslander fears losing one of the best politicians he said the country has had in his lifetime.
He threw his support behind Joyce, questioning whether you "shoot your best horse because he jumped the fence and was found in the neighbour's paddock".
ANDREW BROAD
The Victorian MP says Joyce made an error of judgement and he's still waiting to see if there has been an abuse of power.
KEN O'DOWD
The Queensland backbencher believes the ball is in Joyce's court when it comes to his future, but something needs to be resolved.
LLEW O'BRIEN
The fellow Queenslander admits there are obviously people concerned about the crisis engulfing Mr Joyce, but just as many, if not more, are supportive of him.
MICHELLE LANDRY
The party's whip has been standing by her leader, but says people should wait to see what pans out after his week on leave.
JOHN WILLIAMS
The senator known as "Wacka" was one of the first to warn any revelations about the misuse of public money would mean trouble for Joyce, but has expressed confidence in him.
ANDREW GEE
The NSW MP says he hasn't been approached by anyone talking about a Joyce challenge.
LUKE HARTSUYKER
The former minister believes Joyce needs to work through his issues, but the coalition can move on together with him at the helm.
DAVID GILLESPIE
The backbencher, who is facing his own High Court fight about questions over his eligibility, says he supports Joyce at this difficult time.
KEVIN HOGAN
The member for the NSW seat of Page has no doubt Joyce is feeling very bruised, but has talked up the job he has done leading the party.
MARK COULTON
The NSW MP has kept his head down since the news broke, telling one paper he had "no comment" on Joyce's future.
