Pauline Hanson arrives in Perth

Pauline Hanson has arrived in Perth ahead of the swearing in of three One Nation members into the West Australian parliament.

Premier Mark McGowan said he had spoken with the party members, who will be sworn in this week, adding Labor would pursue its legislation and work with the One Nation MLCs.

"They all seem like nice enough fellows and I'll do my best to deal with them," he told reporters on Sunday.
