Contenders, Liberal's Bob Baldwin and Labor's Jim Arneman, have announced almost "me-too" policies to tackle the noise challenges when Defence's Joint Strike Fighter comes into use.

Mr Arneman this week followed the lead of incumbent Paterson MP Bob Baldwin announcing a three-point plan to tackle the controversial JSF noise issue.

Parliamentary Secretary for Defence Mike Kelly joined Mr Arneman for the announcement.

Mr Baldwin has pledged a runway extension and a second instrument landing system if the Coalition wins government while Mr Arneman has backed a feasibility study into the idea.

Both support new committees to investigate ways to reduce aircraft noise, a recall of Defence's 2025 ANEF maps, and a moratorium on the proposed Kings Hill estate.

While the plan is almost identical to that recently released by Mr Baldwin, Mr Arneman said a December deadline separated the two.

"The back of an envelope announcement that Bob Baldwin made last week, with no time frame is unlike this which has a time frame for the end of the year," Mr Arneman said. Mr Baldwin said Mr Arneman had no understanding of the issue.

"Mr Arneman has no idea about the issues and has placed his faith in Mike Kelly who has already said he doesn't believe there is anything more that can be done to help residents," Mr Baldwin said.
