1950
The Corio and Norlane suburbs grew rapidly post-WWII, driven by industries like Ford, Shell Refinery, and Pilkington Glass. Schools were built quickly to accommodate large student populations, some nearing 1000 students. However, by the end of the century, the area's school-age population declined due to industry loss and natural ageing.

2000
By the turn of the century, nine schools served the area, all seeking government support to revitalise or rebuild ageing infrastructure. With limited funding, a comprehensive regeneration plan was developed, not just to update buildings but to create modern educational spaces. The plan proposed four campuses for Years Prep-8 and a central senior campus for Years 9-12.

2007-2010
Rosewall Primary merged with Corio Primary in 2007. By 2010, several schools—including Corio South, Corio West, Corio Bay College, Flinders Peak Secondary, Norlane High, and North Shore Primary—were closed.

2011
Northern Bay P-12 College was established as Victoria's largest multi-campus school. The Flinders site had closed by this year, and construction was temporarily held at Norlane High School.

2012
Students remained at Corio South, now the Vermont Campus, until other campuses were ready.

2013
By 2013, the final five-campus configuration was completed.

2020
Seventy-five percent of the rebuilds were completed, with the final sites expected to be finished in the upcoming budget years.

2022
The rebuild of the Goldsworthy 9-12 Campus began.

2024
Term 2 marked the start of the move into the new Goldsworthy campus.
