Background. Paediatric patients in Australia experience lengthy wait times for Primary and Allied Healthcare Service (PAHCS) appointments. This results in a lack of satisfaction and adverse health outcomes. However, very few studies have explored wait times for appointments with PAHCSs in Australia. This study explored the length of wait time and associated barriers to timely access to paediatric PAHCSs in Australia. Methods. The scoping review followed PRISMA‐ScR guidelines for Preferred Reporting Items for Systematic Reviews and Meta‐Analyses. We comprehensively searched for relevant studies from five databases, including Scopus, Emcare, Medline (via Ovid), CINAHL, and Google Scholar in August 2023 without any time limitations. Studies that reported qualitative findings on the wait times and associated barriers to timely accessing to PAHCSs were selected in this scoping review. We performed a reflexive thematic analysis using NVivo software in this review. Results. A total of seven studies out of ninety‐one retrieved records were eligible to be included in this review. Studies show that Australian children, in general, had to wait more than one year for health assessments and interventions in PAHCSs. The long waiting times were perceived as frustrating and worrying by caregivers of children. Several overarching themes related to the barriers of timely accessing to paediatric PAHCSs in Australia were identified, such as strict appointment criteria for children, disparity between demand and provision, parental unawareness, and inadequate public funding in rural PAHCSs. Conclusion. Australian paediatric patients are severely burdened with long wait times for appointments with PAHCSs, primarily, due to the poor government initiatives in rural PAHCSs. This study suggested that the criteria for booking an appointment in PAHCSs need to be simplified. Besides, adequate public health funding and the provision of resources are required in rural PAHCSs.
