Millionaire philanthropists, Judith and Trevor St Baker, have vowed to avoid funding the Queensland Children's Hospital in the future over its name change.

Health Minister Steven Miles announced South Brisbane’s Lady Cilento Children's Hospital would be renamed in September last year, following a campaign that argued there was confusion about whether it was a private or public hospital.

Mr and Mrs St Baker were major funders of the Starlight Express Room but have told the hospital's board they will no longer support them following the name change decision as they were displeased by the decision to scrub the name of the pioneering doctor from the hospital.
