Opposition Leader Sussan Ley has rubbished rumours she could be rolled by conservative MP Angus Taylor in a leadership challenge within weeks.
Ms Ley said she has continued to have ongoing policy discussions with Mr Taylor as federal parliament resumed.
"These are ridiculous speculations and they're made by people in the media," she told ABC TV on Wednesday.
"They are not the conversations that I'm having with colleagues and they're not the focus of my team."
Several Liberal MPs have speculated there may be a challenge to the party's first opposition leader as early as the coming week, though Mr Taylor may not have the numbers to carry a spill motion.
It is understood Mr Taylor won't move a motion during the current sitting week to allow the party to scrutinise the Albanese government over the interest rate hike announced on Tuesday.
Liberal MP Andrew Hastie dropped out of the race after a meeting between Ms Ley's rivals, paving the way for Mr Taylor to contest the top job.
But moderate senator Jane Hume said no challenge had been laid down.
"There's no doubt that things are in a state of flux at the moment," she told Sky News.
"I can understand how frustrating this must be for Liberal supporters, but what I will tell you is that our job up here right now is to hold the Labor government to account."
While Ms Ley is grappling with speculation about her own role, she is confident she can reunite the coalition by the end of the week after a messy political divorce with the Nationals in January.
"The coalition can re-form this week with conditions that are supported by the overlying majority of my party room," Ms Ley told reporters in Canberra.
The Nationals needed to agree that shadow cabinet solidarity was mandatory and the joint opposition party room had primacy over any individual party's wishes, the Liberal leader said, adding three Nationals senators who crossed the floor over contentious hate crime legislation need to face consequences.
She will meet with Mr Littleproud on Wednesday to continue negotiations, but the Nationals leader said he backed his senators.
"I'm not going to rule anything in or out," Mr Littleproud said.
"Three of my senators were sacked when they shouldn't have been, and unless that was rectified, we couldn't work with them."
