Martial Arts in Melbourne
Ages 4½ to 15 in Thornbury

Our kids martial arts classes teach children aged 4½ to 15 practical self defence, confidence, focus and respect, in three age groups so every child trains with kids their own age and size. Classes are self defence based, with our Kids Life Skills programme built into every class, and are taught at our full-time dojo at 272 Dundas St, Thornbury under Craig Guest, teaching in Thornbury since 1997.

Fun, high-energy 45 minute classes that build coordination, listening skills, confidence and the basics of self defence, through martial arts games and drills.

A wider range of skills, including wrestling so children learn to control a partner without injury, plus strikes, escapes and weapons basics.

Practical self defence for older kids and young teens, including Knife Defence, the Hanbo and Bo staffs, and real-life scenario training.

Enrolling her at this school has been hands down the best thing we as parents have done for our daughter. GMA is a positive environment for young people delivering a consistent and overwhelming positive message in a sometimes negative world.

My 2 youngest children attend twice a week and have a ball, not only do they learn a martial art, but their confidence has gone through the roof, they are doing hand stands, cart wheels and rolling confidently.

We teach children how to handle bullying the smart way: staying aware, using their voice and body language to set boundaries, walking away and getting help, and only using physical techniques when they genuinely need to protect themselves. Read more in what you can do about bullying, or see our kids self defence classes.
…her confidence has really grown. She’s learning to defend herself and also enjoys the mat chats about friendship, gratitude, respect and other values.

My young son has been attending Guests Martial Arts for over three years, and it's really helped him with agility and coordination, and increased confidence in his physical abilities. … Lessons include discussions about things like friendships, positive social behaviour, sensible risk taking, and there are also reward programs for reading and good manners.

Many parents search for kids karate, so it helps to know the difference. Karate focuses mainly on punches, kicks and blocks. Our kids martial arts include strikes and kicks too, and add throws, safe falling, escapes from grabs and holds, and control techniques, so children learn to protect themselves without having to hurt anyone. All of our kids classes are self defence based rather than tournament based.
Brilliant school- set up really well for kids (and adults), multiple classes divided by age, very motivating for kids to progress through belts, teachers all great with kids and supportive, additional discussions on discipline and motivation…

All new Ninja Stars and Samurai Warriors members go into a draw to win one of 10 NINJAGO LEGO sets, about $2,500 worth of LEGO in total. The draw is live on Facebook on 14 February 2027. We run a different LEGO theme every 6 months: the last one was STAR WARS, and the next might be HARRY POTTER.
Instead of paying Google or Facebook, we thought we would have a bit of fun and give it to our members instead. To enter, try our Free Trial Classes and join the school by 31 January 2027. Students who refer a friend who joins also go into the draw. Winners must still be training at the dojo on the day of the draw. Speak to reception for more details. Conditions apply.
