Member for Calare Andrew Gee has labelled a Liberal Party's submission to abolish the Calare electorate as "flawed" and "wishful thinking rather than serious demographic analysis".
Mr Gee's comments and the Liberal Party suggestion are included in submissions to the Australian Electoral Commission on the redistribution of Federal electoral boundaries.
The NSW Nationals have lodged a submission suggesting Cowra Shire move from the Riverina electorate into the Calare electorate.
The Nationals proposal would also impact Parkes Local Government Area with the state party's submission calling for Parkes to be included in a suggested division of Parkes.
Mr Gee has suggested Calare remain as it is stating, in relation to Cowra, "it is possible the National Party submission eyes political gain by a boundary change in that direction, there is not a strong community of interest between the Cowra LGA and the greater Calare electorate".
"The addition of Cowra LGA would result in the electorate of Calare representing the regional centres of Mudgee, Orange, Bathurst, Lithgow, Oberon and Cowra and risk falling outside the AEC's redistribution requirements should any further population growth occur in Central Western NSW," he said.
The Liberals, in their submission, point out "Labor and the Nationals agree on the additions to Riverina and make few or no changes to Calare".
However, the Liberals have suggested Orange and most of the Cabonne local government area could shift from Calare to the seat of Riverina.
NSW Labor's submission leaves Calare unchanged.
"Should Cowra be repositioned into the Calare electorate, voters from Cowra would be enrolled to vote under their third electorate across four election cycles," Mr Gee said.
"The interests of the residents within this community are not served best by yet another boundary change."
He suggested any changes should be "westwards to Forbes as opposed southwards to Cowra" submitting the Forbes community has a stronger community of interest with Calare.
