Parents of Ulladulla High School students are planning a public rally in an effort to have a second high school, or senior campus, built in the district.
A parent of two UHS students, Grant Schultz says the community is up in arms after the Department of Education announced recently that plans for a second campus had been scrapped.
While he welcomes a proposal to build a new Budawang Special School on the former Shoalhaven Anglican School site in Milton, he says UHS is also overcrowded and the department must plan for the future.
"Ulladulla and district residents are outraged that the Department of Education has taken the extraordinary step of advising that it will no longer expand the Ulladulla High School into the former Shoalhaven Anglican School site," Mr Schultz said.
"This is despite a petition requesting just that, signed by over 10,000 residents, and also follows no less than two years of community consultation in which we were repeatedly informed that such a development would take place."
Mr Schultz says the sell-off of another community-owned parcel of land in Mollymook has added fuel to the fire.
"The Garside Road education precinct was rezoned -and rezoned outside the normal rezoning practice through council - to residential, and is currently for sale," he said.
"This is a disgraceful and despicable act by the Department of Education and residents, parents and people all across this region are rightfully furious."
State Member for South Coast Shelley Hancock has been contacted for comment.
