Liberal Senator Jacinta Nampijinpa Price has reaffirmed her call to end "mass migration", arguing the federal Liberal Party must stop being "Labor-lite" if it wants to return to government.

The Northern Territory Senator, who was sacked from the shadow frontbench last month after refusing to back deputy leader Sussan Ley, told supporters in an email that "there are some who are too focused on appeasing sectional interests and trying to tick off identity boxes".

"And this is no path to government," she says.

Senator Price, who was widely criticised by colleagues over her false claim that Labor was importing Indian migrants to boost electoral support, said the Coalition's core values are "family, community and nation".

"And we need to relentlessly prosecute policies that appeal to, and benefit Australian families, communities and the nation," she said.

In her message, she outlined several policy priorities, including: "Stop mass migration. Build family homes"; "Cease classroom indoctrination. Teach the basics."; and "End Net Zero. Restore cheap energy."

Speaking on 2SM last week, she said the opposition must quickly release its energy and migration policies if it wants to be seen as a credible alternative to Labor.

"I think we have to start lifting the debate to that which unites us, which is family, community and nation," Senator Price said.

"You know, I've urged people and members who have decided to leave not to do that, because ultimately, if you want to see the Liberal party that reflects you, then you've got to be part of that in order for it to do that."

Addressing internal party divisions over immigration and net-zero, she noted that both she and Liberal MP Andrew Hastie — who resigned from the shadow cabinet earlier this month after a split with Ms Ley — will now be able to cross the floor as backbenchers.

"We've got to draw a line in the sand," she told 2SM. "We've got to stop being Labor-lite, and we've got to become a point of difference to the government, because the government is ruining this country, and we have to start calling them out, instead of trying to take each other out."

Senator Price has previously defended Mr Hastie, who claimed immigration was making Australians "feel like strangers in our own home" — a remark echoing British MP Enoch Powell's infamous 1968 "Rivers of Blood" speech. She described Mr Hastie as a "man of principle" who has her "full backing".

The Liberal Party remains divided over immigration and energy policy following its heavy losses at the May election, which reignited debate over the party's future direction.

Conservative figures — including Senator Price's ally, former Prime Minister Tony Abbott, and his former chief of staff Peta Credlin — have urged the party to double down on culture war issues.

Moderates, however, argue that the Coalition's poor performance in metropolitan areas shows the need to move away from divisive rhetoric.

In her email to constituents, Senator Price dismissed calls to prioritise policies aimed at city voters.

"Focusing on how to win a handful of votes from a handful of constituencies is a path to winning zero votes," she said.

"Instead, our focus should be elevated on what unites us as Australians."
