That's how Curtin University expert political analyst Professor David Black has described the WA National Party's amazing effort at the weekend's State election.

"It was a strong performance when it looked as if they could easily have died," Prof Black said.

In Farm Weekly last month during the five-week election campaign, Prof Black said the WA Nationals were on the brink of political extinction.

However, he was singing a different tune on Monday, hailing the party's historic performance and heaping praise on its leader Brendon Grylls and his visionary strategy to win the balance of power.

With votes still being counted on Monday and the State's political landscape drifting further and further in unchartered waters as Mr Grylls met to offer his royalties for regions policy to the leaders of both major parties, Prof Black said there were three possible outcomes to form a government.

He said the most likely was the creation of a coalition between the Liberals and the Nationals, followed by the chance of Labor-National government.

The third possibility was Labor retaining government with the help of Independent MPs if it won the five remaining undecided seats.

Prof Black said Labor's chances were remote of winning the five and gaining the support of MPs such as Kalgoorlie Independent John Bowler.

Prof Black said the Nationals were in a strong position holding the balance of power and would be most likely to go with the Liberals if their regional royalties policy and other requests were supported.

However, he stressed the situation was "highly fluid" and that "anything was still possible".
