One Nation has imposed stricter rules on its members to prevent media engagement, following internal tensions over leader Pauline Hanson's controversial remarks about Australia's immigration policies.

The party's leaked memo warns against speaking to journalists or inviting them to events, citing the risk of undermining the organisation's efforts.

Barnaby Joyce, a key ally of Hanson, defended her comments during a televised appearance, insisting she does not support the White Australia Policy but criticises current migration practices.

Prime Minister Anthony Albanese condemned Hanson's overseas trip, calling it inappropriate for an Australian senator to engage with fringe groups.

The party's disciplinary measures come as political tensions rise, with opposition leaders questioning One Nation's viability as a governing force.

Despite these challenges, the party remains competitive in recent polls, highlighting ongoing debates about immigration policy and national identity in Australia.
