The Greens have repeated their calls for root and branch reform of Australia’s political donations and election spending regime with billionaire Clive Palmer shamelessly bragging about his plans to spend his way to electoral success.

A Parliamentary Library Brief, provided to the Greens, reveals that a minority parliament is only 828 votes away, and looms as one of the most likely outcomes after the next election.

The brief showed that anything between a 0.57% and 3.88% swing to Labor would result in a balance of power scenario. The average swing in the last 20 years of Australian elections is 2.8%.

“Assuming all six 2019-elected crossbenchers (excluding Craig Kelly) and only these six get returned, a 0.57% uniform two party preferred swing to Labor will knock the Libs into minority.
