UPDATE 11.11PM: SUSAN Lamb is declaring victory in Longman.
The mum from Dakabin said she is feeling overwhelmed by the outcome, but it is the result of hard work.
Meanwhile the Australian Electoral Commission is yet to call the seat in.
"Well today was really a culmination of over 12 months of campaigning - speaking to people, listening to what their concerns are, listening to what their concerns were in their lives and what really mattered to them," she said.
"Today was really enjoyable day. We knew what was important to people and we knew they were coming out to vote on those key issues.
"It's Medicare, health and hospitals. It is education and is about the infrastructure that's needed for us to work and live and that's the NBN. But that stuff didn't just come out it came out because we listened to people."
Mr Roy is yet to concede defeat.
"He hasn't conceded via phone to me although we are declaring victory," Lamb said.
EARLIER: A FORMER union organiser in Longman appears to have ended the career of Australia's youngest politician and the youngest Member of Parliament to be made a Minister.
Labor's Susan Lamb was last night holding 51.19% of the two-party preferred vote, an improved of 8.11% on its 2013 result and a lift of 5.72% in Labor's primary vote.
A swing of that size nationally would have by now elevated Labor to government, something unlikely to be determined soon after close contests in seats across Australia.
Ms Lamb has attracted 22,426 primary votes representing 36.04% of the 62.17% of the vote which has been counted from 32 of 39 polling booths.
Mr Roy has secured 24,439 votes or 39.27% of the counted vote which may not be enough to protect him from the flow of preferences to Ms Lamb.
The former Matthew Flinders Anglican College student at Buderim who grew up on a farm on Pumicestone Passage, was elected to Parliament in 2010 as a 20-year-old.
