The annual dinner for the Millicent and Rendelsham branches of the Liberal Party will be held at the Grand Hotel in Millicent on April 22.
As well as a meal, the annual general meetings of the two branches will be held along with addresses from Member for Barker Tony Pasin and Ben Hood MLC.
It will be the first such function since 1999 the local MP has not been a Liberal Party member.
Liberal Party candidate Nick McBride won a second term as member for MacKillop in 2022 but quit the party last year to sit as an Independent.
