Clive Palmer and his staggering $60 million spend on United Australia Party's election campaign has only managed to secure 20,000 more Senate votes nationally than a minor party forced to "scratch around" just to field candidates.

As of Sunday afternoon the Help End Marijuana Prohibition party had secured 141,500 first preference Senate votes or 1.9 per cent of the national vote, just behind UAP's 161,000.

The HEMP party had its best showing ever this election.

It's the party's best result since being registered in 2010 and is a huge jump in support from the 2016 election when the party entered a joint ticket with the Sex Party in several states and received 106,000 votes.

Speaking from the Hemp, Health and Innovation expo in Sydney the party's president Michael Balderstone said he was happy with the results given the advertising spend of bigger parties and they would probably make the party take the next election "a bit more seriously."
