The Australian Electoral Commission (AEC) has declined a request from the Greens and the Australian Sports Party for a vote recount of the WA Senate results.

Greens Senator Scott Ludlam says he will appeal the AEC's decision.

Under current numbers the final two Senate seats for WA have gone to Palmer United Party (PUP) candidate Zhenya Wang and sitting Labor Senator Louise Pratt.

There was a difference of 14 votes between the PUP and ALP candidates finishing fifth and sixth over the Greens and the Australian Sports Party.

But the AEC says the requests for a recount did not identify any specific issues, which would have warranted the conduct of a recount.

Senator Ludlam says scrutiny is warranted considering the slim margin between the candidates.

"There have been Senate vote recounts both in this state and other jurisdictions when the margin has been far greater, and in more than one occasion those re-counts have led to a different result," he said in a statement.

"In such a marginal decision, with such important consequences for two Senate seats, only a recount can ensure that the votes receive the scrutiny needed to exclude human error.

"As none of the elected senators will be required to take their seats in the Senate before 1 July 2014, there is time to ensure the result is correct."

The formal declaration of the WA senate poll will now be announced Friday morning.

The Liberal Party's David Johnston, Michaelia Cash and Linda Reynolds and the ALP's Joe Bullock won the remaining seats.
