Pauline Hanson's One Nation is expecting to field dozens of candidates at the next South Australian election, but experts have predicted it will be tough for the party to cut through.

The party's immediate focus is on the West Australian election next month where it is fielding more than 50 candidates.

But One Nation's South Australian administrator, Steve Burgess, said it was already looking ahead to South Australia and the March 2018 election.

"At a state level, we endorse Pauline Hanson as the party leader. It's her profile and her leadership and really it's her vision," Mr Burgess said.

"The people I speak to on the street tell me that what Pauline Hanson is saying is what they want to happen."

Mr Burgess said One Nation would be a "prominent player" in South Australia, after the party's resurgence in last year's federal election and a strong showing in Queensland and WA.

The small business owner, former soldier and One Nation Senate candidate in the 2016 election said there was mood for change.

"There's a lot of dissatisfaction out there and I don't think the opposition is giving the answers that people are looking for," he said.

"The contest will be interesting, we've got boundary distribution, we've got a government on the nose, and we've got an opposition that hasn't really put forward the image that gives people confidence.

"So obviously with One Nation on the scene and [Senator] Xenophon, anything could happen."

Mr Burgess said he had received at least 30 enquiries from people interested in running as Upper and Lower house candidates and that the party would run as many "qualified candidates" as possible.

But first, it needs to recruit 200 members, to be eligible to register with the Electoral Commission and be a player on the day.

It will be Mr Burgess' job to vet candidates, something that has not previously played out well for One Nation.

"We can't waterboard them and we can't put them under a lie-detector test," he said.

"Will we have what's happened in other states? Quite possibly. So could [unsavoury revelations about candidates] happen to us? Yes it could. Am I concerned? Yes I am, but I'll do my utmost to make sure it doesn't happen."

Mr Burgess does not believe any political party, including NXT, will be a threat to One Nation in South Australia.

'Very crowded house' at next year's election

But Flinders University political expert Haydon Manning disagrees.

He has cautioned against using Queensland — or to some extent Western Australia — as a test case, labelling South Australia a "different kettle of fish".

"Really it's a very crowded house on the right in South Australia looking towards March 2018," he said.

"We've got Family First, obviously One Nation are looking at putting candidates up and of course there's that other big choice, Xenophon."

Mr Manning also expects Liberal Party defector Senator Cory Bernardi to form the Australian Conservatives and to have a presence.

"I can't see how Bernardi, having broken away, formed a party, launched a website, trying to attract members, cannot but stand candidates," he said.

"Certainly the Upper House. I cannot see how he won't run a candidate, but also many Lower House seats, so there's another choice for voters on the right."

Senator Bernardi said previously — and again via text message to the ABC — that he has no plans for the South Australian election.

Mr Manning said the state's voters would head to the polls after 16 years of a Labor Government, with a bolstered Liberal Party, in part because of an electoral boundaries redistribution and the entry of some new parties.

"The big question is, will there be the swing to remove a government, with voters saying 'I've had enough of Labor' and vote Mr Marshall in, or are we going to see the sense of volatility and doubt among voters about the major parties and that vote goes to Xenophon, One Nation or [whomever]?

"That's why I say this is going to be the most difficult election, certainly at this juncture, to get any sense about how it will pan out."

While doubts remain over the number of candidates, the seats they will run in and the parties they will come from, there is no doubt about which issue will dominate.

"Without a shadow of a doubt, if we have blackouts next summer, it'll be super huge," Mr Manning said.

"But even without that, the question of energy prices, energy reliability, and the whole period of the Labor Government oversight of the electricity grid in South Australia will be right in the centre."
