The new facility officially opened on March 27 and according to a spokesperson has the capacity to deliver more than 13,000 cancer treatments annually and create more than 30 immediate jobs in healthcare, growing to 60 jobs as services expand over time.

The new centre "brings advanced cancer care closer to home" for the South West Sydney community and people living in the Southern Highlands.

The four-storey development has the ability to upscale and increase capacity to meet future demand in the region as the population grows and ages.

GenesisCare offers radiation therapy, chemotherapy, haematology, and selection into clinical trials and research programs at the new centre, with plans to offer Theranostics and nuclear medicine in the future.

Patients can also access pathology and allied health services offered under the same roof, with diagnostic imaging to be available in the coming months.

The development is the result of a partnership between Campbelltown City Council, cancer care provider GenesisCare, construction company Erilyan, and Northwest Healthcare Properties.

Politicians, local leaders, doctors, and key community members officially opened the building, marking the completion of Stage One of a multi-staged health precinct being developed.

"The site is designed to meet the critical and rapidly growing need for private healthcare in the thriving Macarthur region," a spokesperson said.

"The precinct is surrounded by green open spaces such as Koshigaya Park and is conveniently located close to Narellan Road and the M5, creating ease of access for patients travelling to and from the centre from the wider region."

NSW Health Minister, Ryan Park, said the "fantastic" new facility would provide greater access to cancer treatments for the local community, closer to home.

"One of the key services offered at the centre is radiation therapy, with the majority of the treatment costs covered by Medicare depending on individual circumstances," Mr Park said.

GenesisCare's NSW general manager Richard Briggs was proud to begin treating patients closer to their homes.

"GenesisCare strives to provide high-quality care that's personalised and tailored to the patient," he said.

"We always aim to treat the person not the condition. Our services will complement and work with existing cancer treatment providers in Campbelltown, supporting one of Australia's fastest growing cities.

"Our doctors are well established in the local area. They either work, live and teach in South West Sydney and know this community well," Mr Briggs said.
