Pauline Hanson is seeking support from her Senate colleagues for a national vote on migration levels.

The One Nation leader will on Monday ask the upper house to support a plebiscite, arguing the country’s roads and health system are buckling under the weight of new migrants.

“The Australian people have never been given the opportunity to actually hold a plebiscite into how they feel about the current rate of immigration into Australia,” Senator Hanson told reporters in Canberra.

Government Senate leader Mathias Cormann did not rule out supporting her calls for a national vote, but said work was already underway to manage migration levels.

“Of course we have already made a judgement in the most recent budget to cut the immigration levels,” he told reporters.

“So we’ve made judgement ourselves in relation to these matters, but I haven’t seen the specifics of what Pauline Hanson is proposing.”
