Dr Phelps is fighting to retain the seat she won after a resounding 20 per cent swing against candidate Dave Sharma in the October by-election.

But on Friday night her posters were taken down in several locations along New South Head Road at Rose Bay, at Bondi and in Elizabeth Bay, Dr Phelps said.

"Well I think it's pretty obvious that there are some dirty tactics afoot and obviously in a grass roots campaign we rely on donations, we rely on volunteers," she said.

"For our posters to go up and then to be taken down … this happened in the by-election [and] it's happened again, it's incredibly frustrating."

The Liberal Party's posters remained in place, Dr Phelps said, adding: "So you can make your own conclusions about that."

But Liberal candidate Dave Sharma flatly denied having anything to do with it, saying his posters had suffered the same fate.

"I completely reject Dr Phelps's intimation that me or my team had anything to do with the removal of posters. It's nothing more than an unfounded and baseless allegation," he said in a statement.

"I too have had some of my posters stolen overnight. We absolutely condemn the removal of any candidate's posters."

'I am the incumbent'

A similar claim was made during last year's Wentworth by-election, with Labor's Tim Murray, Dr Phelps and Justice Party candidate Ben Forsyth all blaming Mr Sharma's team over the disappearance of their posters.

Mr Murray attacked Mr Sharma on Twitter and even alleged Labor posters were taken down and replaced with Mr Sharma's.

He shared two photos — one showing a power pole with Mr Murray's poster attached, and then another showing Mr Sharma's in its place.

Dr Phelps said it was clear the motivation this time around was to reduce her visibility as a candidate.

"The people who are taking down these posters clearly feel threatened — it's a tactic of desperation," she said.

"I am the incumbent member for Wentworth, I am defending that role and the Liberal Party don't want me to win the next election."

Wentworth is the country's second smallest electorate, covering 38 square kilometres, and includes some of the country's most exclusive and expensive real estate in areas such as Vaucluse and Double Bay.
