Greater representation for the Nationals in the coalition leadership team and the direction of climate policy remain unresolved, as they thrash out a deal with the Liberal party.
Liberal leader Sussan Ley and Nationals counterpart David Littleproud have held their first formal talks to set up a coalition agreement between the parties, which is negotiated after every election.
Mr Littleproud travelled to Ms Ley's home in Albury, regional NSW, for the face-to-face meeting on Thursday.
It was the first of many discussions, which continue over coming days to lock in a deal.
The coalition agreement will help to determine how frontbench positions are carved up between the parties in the next parliament, as well as positions on policy.
Ms Ley said "productive conversations" were held about a range of matters.
"Very convivial, very friendly, and obviously, as I will always say, matters that the Nationals discuss in their party room are for them, and matters that the Liberal Party discuss in our party room are for us," she told reporters.
The opposition leader accused Anthony Albanese of neglecting rural and regional Australia throughout his time as prime minister.
Issues over whether the coalition keeps its nuclear policy or its net zero emissions targets by 2050 will also feature in discussions.
Nationals senator Bridget McKenzie has called for her party to have a bigger seat at the table.
While the Nationals retained nearly all of its lower house seats at the election, it lost the NSW seat of Calare to Andrew Gee, a former National who defected to serve as an independent.
The coalition has won 43 seats in the 150-seat House of Representatives, and has 26 seats in the Senate, with counting still continuing.
Liberal MP Andrew Hastie has expressed his desire to one day lead the party.
The West Australian was touted as a contender in the recent Liberal leadership contest, but did not put his hand up.
In a podcast interview, Mr Hastie said while family reasons prevented him from standing for leadership, he wanted to eventually lead the party.
Just days into her role as opposition leader, Ms Ley said the coalition needed to listen to the message it received from voters at the ballot box.
