My Gym Hornsby Children's Fitness Centre

About this venue

My Gym Australia – Hornsby delivers fully hosted children’s birthday parties designed around fun, physical activities, music, games and themed experiences in a safe, indoor gymnastics space. Parties are led by trained party specialists who keep kids engaged with age-appropriate activities, lively music and highlights such as the crowd-favourite Space Flight zip-line and a special Birthday March. Party packages provide exclusive use of the gym floor and food area, two dedicated party hosts, themed decorations, setup and cleanup, and My Gym-branded invitations and goodie bags. Options are typically available for 1.5-hour or 2-hour celebrations, and you can customise music, themes and some activities to suit your child’s interests. Current package tiers include Grand, Premier and Deluxe Celebrations that accommodate roughly 10–20 kids depending on the option you choose, with member pricing starting around $579 and an additional non-member charge. Cake cutting service and a special gift for the birthday child are included with most packages, and parents can arrange their own food and refreshments. Parties are best suited for energetic children from toddlers through primary school ages, with supervision and participation encouraged. Booking in advance is required, and standard rules apply (e.g., arrival times, footwear policies and age-appropriate participation). Contact the Hornsby centre for exact pricing, availability and any current restrictions or special package add-ons.
