UNSUCCESSFUL Gilmore candidate Neil Reilly is set to nominate for the Senate if former foreign affairs minister Bob Carr steps down.
Mr Reilly said he hoped to force a democratic ballot after rumours circulated that Australian Workers Union general secretary Paul Howes might fill the vacancy.
"If someone else nominates, they'll have to have a vote, which would force that process to take place," Mr Reilly said.
Neither Mr Carr nor Mr Howes have publicly announced their intentions and the Melbourne-based union heavyweight was not on the ticket during the election.
Gerroa's Glenn Kolomeitz ran fourth on the NSW Senate ticket at the federal election and missed out when voters elected the first two candidates.
However, he would not nominate for the vacancy unless he could be sure Labor's head office in Sydney would use a transparent selection process, he said.
"They parachuted [former NSW ALP general secretary] Sam Dastyari in and now Howes - they call for nominations after they've chosen someone," he said.
"It's pointless [nominating] when head office has already made up its mind.
"Our background is the union movement, but union membership is quite small. So if we're going to be truly representative, we need to have more diverse representation."
Mr Reilly said most branches within the Gilmore Federal Electorate Council, including Kiama, Shellharbour, Bomaderry, Bay and Basin, and Milton-Ulladulla were outraged by a possible parachute.
"Their blood's still up from the election," he said.
He said the votes Mr Howes controlled at ALP conferences did not give him the right to a Senate seat.
"I think there's a sense of entitlement that is misplaced," he said.
