Perth: Pauline Hanson is about to begin her third TV cross of election night and the crowd's energy is waning.

"Keep them bobbing, keep them bobbing," James Ashby, Hanson's mercurial chief-of-staff, yells at the One Nation supporters behind her clutching corflutes.

"Keep the enthusiasm up!"

The man often described as the party's puppet master is waving his hands in the air, trying to rev up the party faithful gathered at Melville Bowls Club in Perth's southern suburbs.
