The head of the WA Shooters and Fishers Party says people's frustration with restrictions on recreational activities has propelled him to a likely victory in the upper house.

With just over half the votes counted, Rick Mazza is on track to secure a seat in the Legislative Council's Agricultural region.

The WA Electoral Commission says the upper house results will not be finalised for at least another week and a half.

Mr Mazza is confident he has secured enough votes to get across the line.

"We only registered the party 14 weeks before election day and were running flat out campaigning for 10 weeks on a shoestring budget," he said.

"The odds were stacked against us but it appears there was enough momentum there."

Mr Mazza says the result was driven by outdoor lovers, annoyed by tough restrictions on activities including hunting and recreational fishing.

"For most people who go into the outdoors to fish or shoot or whatever, the last thing on their mind is politics, they just want to relax," he said.

"But a lot of restrictions have been put on them and I suppose the silent majority has now become quite political.

"We believe that a lot of conservation management, whether that be aquatic or terrestrial, is based on ideology.

"So [although] we're conservationists at heart, we truly believe there are other ways of managing environments without having to lock people out or ban areas."

Mr Mazza points to the party's achievements in New South Wales as evidence it can influence debate and make a difference.

"Even though we might only be a single voice, we certainly want to be a very loud voice," he said.

"In the NSW upper house over the past four or five years, they've held the balance of power, and they've been able to do things like put moratoriums on new marine parks to try and ease restrictions."

He says the party is particularly keen to advocate for changes to firearm laws in WA.

"Over the years, for some reason, firearm owners have been demonised a fair bit but it is in fact one of the safer sports that exists," he said.

"We understand there has got to the regulation, but when that regulation doesn't help public safety and really just makes things very frustrating for firearm owners, then we need to have a look at changes."

In addition to its stance on gun laws and conservation management, the party has strong views on immigration.

The Shooters and Fishers website states the party wants to see a halt on new immigration applications, pending an audit of Australia's natural resources.

It has also called for a referendum to be held to decide on an appropriate population level.
