Background/Objectives: Childhood cancer survivors face long-term cancer-related health risks, and daily behaviours, such as physical activity and recreational screen use, may influence their long-term overall wellbeing. Yet, little is known about survivors’ knowledge and understanding of recommended guidelines or their patterns of structured and unstructured activity. This study aimed to (i) assess survivors’ knowledge of physical activity and screen time guidelines, (ii) describe their self-reported (un)structured activity and screen use across weekdays and weekends, and (iii) examine associations with health-related quality of life. Methods: This secondary analysis used data from a feasibility pilot study of an intervention for survivors aged 8–13 years who had completed cancer treatment at least 12 months earlier. Participants self-reported physical activity, recreational screen use, knowledge of guidelines, and health-related quality of life (HRQoL). We used descriptive statistics and non-parametric tests to analyse behavioural patterns and associations. Results: Over one-third of survivors underestimated or overestimated the recommended physical activity and screen time (35%), whilst 23–50% reported ‘don’t know’. Participation in ‘Physical Education’ classes at school did not differ between summer and winter school terms, yet there was greater participation in structured physical activities in winter compared to summer school terms (median 270 vs. 170 min/week). For unstructured physical activities, 69% reported engaging in a median of 60 min/week at school on most days of the week in summer, whilst most survivors (96%) did not report any unstructured activity in winter. Only 19% met the recommended daily minimum of 60 min of physical activity year-round. Excessive screen use increased from school days (19%) to weekends (46%), notably handheld device screen time. We did not find any significant associations between meeting physical activity and screen time recommendations and HRQoL. Conclusions: Survivors frequently engage in irregular structured and unstructured physical activity levels and increased screen time. These findings emphasise the need for targeted, year-round interventions to improve physical activity, reduce recreational screen use, and support long-term survivorship health.
