Palm Islanders will have access to a bigger and better medical service with the official opening of the Palm Island Primary Health Care Centre on Wednesday.

Health Minister Steven Miles says the $16.5 million centre, funded by the Palaszczuk Government, was vital to the health and wellbeing of people on the island.

All Queenslanders, no matter where they live, should have access to the same world-class healthcare, Infrastructure Minister Cameron Dick says.

The centre is currently operating with two general practitioners, 16 Aboriginal health workers, one dentist and one dental assistant, two child health nurses, two midwives, a mental health clinical nurse consultant and a drug and alcohol clinical nurse consultant.
