In 1997 the current College facilities were built creating an administration building, library, staff kitchen, toilet block, two upstairs classrooms, an undercover area as well as a playground and sandpit play area.

In 2005 an extension was made to the administration building creating a combination art room and home economics room.

A Library & Resource Centre with the latest in computer technology was completed early 2011 with the official opening in April that year. Extensions to the administration building and two accommodation units for staff were completed shortly after. The College celebrated its 25th birthday on Saturday 15th October, 2011.

A new Prep classroom was opened in May 2014, with additional playgrounds and turfed areas.

Middle School commenced at Gulf Christian College in 2015.

In 2016, our Middle School building (Stage 1) was completed with a purpose-built science laboratory/classroom and a manual arts classroom designed to cater for our students from Years 7 to 9.

In 2017, the Middle School Stage 2 was completed, encompassing two classrooms and a Library, as well as a Home Economics room. The existing library was converted into a primary classroom.

The Fred Edwards Sporting Facility was also completed on land across the road from the College. This included covered ball courts, storage and toilet facilities. This facility significantly enhanced the sporting and recreational options for our students.

During 2019-2021, four additional staff houses were purchased to accommodate our teaching staff and their families.

The update and extension of our administration building provided additional offices and a larger staff room to accommodate growth. Primary classrooms upstairs were extended into the verandah spaces, providing larger rooms. This year saw the development of our Sports Oval beside our Sporting Facility.

This building has enabled the College to significantly invite community into the College to embed local language and culture into our curriculum. Our Learning Enrichment Department is also located in this building.

The College has successfully been accredited to include Year 10 and Year 11 in 2025, with the introduction of Year 12 in 2026.
