Palmer United Party will have three senators in Canberra come July, but Greens senator Scott Ludlam has missed out on his bid for re-election.

PUP's Zhenya 'Dio' Wang, who works in the mining industry, has been elected to the Senate in the fifth spot for Western Australia.

But the result has been disputed, with both the WA Greens and Australian Sports Party lodging requests for a recount.

Senator Ludlam confirmed on Wednesday afternoon that the Greens have lodged a formal request for a recount, given there were only 14 votes between the Australian Christians and the Shooters and Fishers Party, with the tight result impacting on the flow of preferences.
