Govt still short on backpacker tax vote

Treasurer Scott Morrison says the government remains one vote short of a majority to get its 15 per cent backpacker tax through parliament.

Mr Morrison held talks with crossbench senators on Wednesday night and Thursday morning.

He told reporters on Thursday the government had three One Nation senators, three Nick Xenophon Team members and Liberal Democrats senator David Leyonhjelm on board and would not engage in a "game of ping-pong" on further change.
