It could be a case of finally getting lucky for Fiona Patten, the long-time sex industry lobbyist who wants to pull back the covers on Victoria's political debates.

Early results are pointing to Ms Patten and her Australian Sex Party securing the last upper house seat in the Northern Metropolitan Region. If she does, she could form an important voting bloc with Labor and the Greens.

The win would be a "coming of age" moment for the four-year-old party, Ms Patten said on Sunday while eagerly waiting for the final numbers to be tallied.

The party was launched in 2009 as a political movement for the adult industry to counter the influence of religion in politics. The electoral commission even held a special hearing to determine if using the word "sex" in the party's name was obscene.
