He has also criticised Australia’s gun laws saying most people have no gun experience and do not know they are “a lot of fun” when used safely.
He was elected in 2013 when the Liberal Democrats polled 9.5%. Critics say it was a result of being in the first column of the large Senate ballot paper and it confused voters who thought they were voting for the Liberals.
The Senator was re-elected in 2016 with 3.1% of the vote, winning enough after preferences to secure the final vacancy at a double dissolution.
The NSW upper house requires a 4.55% quota.
If elected, he also plans to campaign to legalise recreational cannabis which he failed to do in the Senate.
Otherwise, he may become a forgotten Senator and commuter.
