THE state's most marginal seat was too close to call last night with both candidates unwilling to claim victory.
Incumbent Liberal Matt Williams and Labor candidate Steve Georganas were regularly neck and neck on 50 per cent each of the two-party preferred vote. 
When asked how he was feeling, Mr Williams told the Sunday Mail: "I've been better".
Mr Georganas last night told waiting media that the outcome was "too close to call" and he expected a final result could take days once postal votes were counted.
The Georganas clan has multiplied since the last federal election and the newest additions were out in force to support grandpa.
Little Stathi was the star of polling day in 2013 when, as an infant, he joined Mr Georganas on the hustings at the Cowandilla booth. This time it was 11-month-old Mia's turn in the spotlight, as Stathi, who turns 3 next week, was more keen to head off to the park.
Mr Williams took Hindmarsh in 2013, on a 1.9 per cent margin, from Mr Georganas who held the seat since 2004. But an Advertiser-Galaxy poll conducted less than two weeks before the election showed a 50-50 split between the parties in the western suburbs seat on a two-party preferred basis.
Mr Williams said he expected the presence of NXT's Daniel Kirk would make the result harder to predict. "We're just uncertain where those preferences will go," he said.
Mr Kirk said voter reactions gave him the impression the fledgling party was "right in" the contest. "There's now a new option," he said.
Both major party candidates placed Mr Kirk fourth on how-to-vote cards. All three men were expecting a long wait for the result as they greeted voters at booths from early morning.
"I've worked as hard as I can to get some great results using my influence in Canberra," Mr Williams said. "I'm hoping the people will acknowledge the work that I've done to provide a better future for the people of Hindmarsh." Mr Georganas conceded he secured a "wafer-thin margin" in 2004 and he felt this year "will be no different".
