Acrogym

Acrogym hosts gymnastics birthday parties at its own gyms in the Sutherland Shire: 113R Anzac Avenue, Engadine, and the Menai gym on Old Illawarra Road. The published party is exclusive use of the gym for 1.5 hours — one hour of supervised circuits, air-track tumbling and structured games with two accredited coaches, then 30 minutes in the party room. No age range is listed on the official party page.

Two packages are priced for up to 15 children. Fully catered is from $500 and includes pizza, chips, Cheezels, popcorn, a confectionery treat, cordial and water, with special diets at extra cost. Self-catered is from $450 if the family brings food and decorations. Extra children are from $18 catered or $15 self-catered. Extra time is from $110 per half hour on the first or last slot of the day, and a jumping castle can be added from $50. Highchairs are not available. A $100 deposit locks the booking; cancellations 28 days or more beforehand receive a full deposit refund. Parents should confirm prices when booking.

Slots are booked on the calendar at acrogym.com.au/birthdays. Tuesday classes at Menai Indoor Sports Centre on Allison Crescent are separate — parties are not advertised there.
