The basketball court and adjoining wall have been demolished, the piling is complete and the bulk earthworks are underway.

The in-ground services will come next before the building's base slab is poured and then the steel work will go up.

Stage two is divided into two parts.

The work on site at the moment falls under the stage 2A, which a $42 million project funded by Charles Sturt University.

That stage, which has planning approval, features teaching space, offices and a large tiered lecture facility with breakout spaces.

CSU is preparing to lodge a stage 2B development application with Port Macquarie-Hastings Council.

The state government is providing $15.08 million towards stage 2B with CSU contributing another $4 million.

Stage 2B will deliver more teaching spaces and an innovation hub.

CSU announced the campus expansion in October 2018 with Lahey Constructions awarded the stage two expansion construction contract.

The first stage of the campus off Major Innes Road has been open since 2016.

The stage two expansion will also provide more car parking.

CSU executive director of facilities management Stephen Butt said they were really confident the on-site work was on program.

The plan is to finish stage 2A before Christmas in 2020 with stage 2B expected to be ready in very early 2021.

"Growth is strong in terms of student numbers and by 2021 that space will become quite critical," Mr Butt said.

The bigger campus will allow the university to cater to more students.
