“It is an extremely busy road with a bad history of accidents,” he said.

Williams wrote to Education Minister Prue Car about the change and received a response last month from the Department of Education official Taka Bodiam,who said it was due to population growth.

“This is especially the case in areas of high growth like Bella Vista and Kellyville,where enrolment dynamics can shift rapidly,” the reply read.

Ben Zhang from the Kellyville Public School Catchment Action Group said it appeared residents had been displaced to accommodate the influx of residents from high-density developments near Kellyville metro station.

Kellyville Public School has some of the best NAPLAN results in the country. Last year,students in both years 3 and 5 achieved above-average,statistically similar results in reading,writing,spelling,grammar and numeracy.

Mother-of-two Lin Ma said that,while the department would not admit the differences in school reputation or performance,“enrolment patterns speak for themselves”.

“If overcrowding is truly the issue,why are new families from Bella Vista and recently approved apartments being introduced while long-term residents are being displaced?”

Luke Falkner,who bought a house in Kellyville 18 years ago because it was affordable,said he simply wanted his two-year-old daughter to be able to walk to school when she reached kindergarten.

“Kellyville is walking distance whereas Beaumont Hills is not,” he said.

Chirag Anandwala,who has a two-year-old son,said he bought his house in part because it was in the Kellyville Public catchment.

“People are wondering if they will have to shell out extra dollars for a private school,” he said.

A department spokeswoman said:“We carefully consider all factors against the current transport and road connections and the overriding need to manage student population growth using the available school facilities.”
