The Southern Highlands Liberal Party branch executives supported reform in the hopes it would allow each member an equal vote.

"NSW is the only state in Australia which does not have some sort of plebiscite structure," Moss Vale president Michael Ball said.

At the moment, major decisions were made by a select few in the NSW State Executive, for example, Liberal candidates for council elections needed the backing of the executive which overrode the wishes of the local branches.

Meanwhile, the branches were fighting to ensure candidates who did not have local support would be a thing of the past.

"Prior to the 2012 election, the branches wrote to the State Executive asking that there be no Liberal Party involvement in council," Mr Ball said.

"Local government decisions can and do alienate voters because they cannibalise time and money which should be devoted to state and federal elections.

A Party Reform Committee was recently set up by the State Executive to "ensure the party is best placed to win elections and engage with the broader community" and "to make party membership more meaningful."

However, the committee has been criticised because it was largely made up of lobbyists including former powerbroker Michael Photios.

A damning letter by Brookvale Liberal Walter Villatora to other members, aqcuired by Southern Highland News, stated "the committee's principle purpose is to delay meaningful debate for as long as possible through a cumbersome process".

"This committee confirms the State Executive is not sincere about democratic party reform. This is a process that needs to be driven by the membership," he said.

Mayor Juliet Arkwright, a member of the State Executive, said the overwhelming majority of members wanted the committee to build the way for a plebiscite protocol for all NSW Division pre-selections.

"The members rejected most forcefully the manner of the proposed plebiscite at the time, but accepted its establishment in principle," she said.

"I, along with this considerable majority, was of the same opinion. I have every confidence that the members of the NSW Division of the Liberal Party of Australia will accept a suitable proposal for plebiscites."
