It used to get into a fair bit of trouble when I was younger.

And now that I'm interested in parkour I realise it's becauseI wasn't interested in anything,

I didn't have anything to do.

That first step, realising that you can give it 110%,

you can commit with your body, and can spring in to that jump,

and realise that, oh, even if I land and jump off the other side,

it's still okay. I'm not going to crash and burn.

I believe it does change the way you look at the world.

The art of moving efficiently through urban environments, known as parkour,

is both a sport and a discipline.

More than 20 years after it's birth in France in the late 80s

parkour is thriving in Australian cities.

I'm Dominic di Tommaso, 24 years old,

I am part of Crew 42.

My name is Max Masters,

I'm 25 years old, and I've been doing parkour for almost nine years.

Max and Dom are two of the founding members of Crew 42,

one of the top parkour groups in Australia.

Is it a business, but it originally started out as a group of mates,

just having fun and trying to capture that.

I have a strong team of six,

and we do professional work quite often, probably once a month at this stage.

We're training together twice a week.

We've done a few different things like a car show performance in China, and

we work at a lot of different companies like Panasonic.

I get to be part of an exclusive group of parkour, which happens to represent Sydney as a whole.

So i can say that I am Sydney Parkour.

Both Max and Dom starting training around the same time,

but they came from very different backgrounds.

I identify as Islander Australian.

My mother is from Papua New Guinea,

and my father is from the Cook Islands.

My father left us when I was quite young.

My mother suffers from a mental condition, paranoid schizophrenia.

From the age of six until about 13, me and my siblings were in foster care.

There was one time, for maybe half a year, where I actually didn't have a place to stay,

As a kid growing up and going to high school, I found it really hard to focus on things like study, and

reading books and getting ready for tests.

I wasn't focused enough from all the unstable trauma that was happening in my life at the time.

I didn't really finish high school.

I used to hang around with a group of guys who were really quite aggressive and violent.

I was charged with assault occasioning in actual bodily harm.

I thought I was going to end up just like everybody else in my neighbourhood.

There wasn't much hope back then.

I used to have a youth mentor who would take me around to different places.

One day he showed me parkour on youtube,

and I couldn't believe it.

I was like a huge green light, saying YES.

I had a full time background in figure skating,

I also did ballet and dance full time.

I've won the Australian Championships for ice skating four times.

Something like falling on the ice 100 times a session when I was younger,

to now falling on concrete once, it's a little bit easier to deal with.

I was always doing sports, and channeling my energy into sports with all these guidelines and restrictions,

And then one day, on the internet,

I saw a parkour video, and went, 'people can do this, legitimately?'

Like they just run and jump, they don't need guidelines or rules?

Dom is a sponsored athlete.

He's also part of another crew, Team Farang,

a collection of elite parkour athletes from around the world.

Parkour has taken me to Thailand, it's also taken me to China, multiple times,

I've been to Holland, I've been to Spain, I've been to France, I've been to Italy,

I think the biggest feeling of elation I've had has been a jump called the ManPower gap.

Five stories high on to a four story roof, death drop in between.

Currently in Australia, as a professional parkour competing athlete

I believe I am the only one making enough to get by and travel.

There is no strict guideline - it's not like you start start in the mailroom of parkour

and work your way up to CEO.

So when you do your slide over the box, you want to think about where you're going to land...

Both Max and Dom are giving back to the sport that changed their lives.

and training the next generation.

Not everyone who is doing parkour is jumping from 40 story rooftop to 40 story rooftop.

That's just what you see in the internet.

There's a lot more of a deeper side, and a lot more that's come in at ground level.

It's something that can really teach people to overcome obstacles both mentally and physically,

and to be more confident in themselves.

Today, what we're going to be doing, is learning our web stuff.

I'm 14, and I've been doing parkour for just over a year.

Even when it seems like they're really good, and they're not going to bother with someone who is new,

you'd be surprised at hour friendly everyone is,

and how much they love to help out.

-How to you find it here? -Good, really good.

The guys here are like family.

So when you roll, you come down to your shoulder, but you come over it,

looking up the whole time...

The general atmosphere, within the parkour community,

is just positive.

Everybody's just accepting of one another,

age, race, gender, it doesn't matter.

I believe that Max is easily on the same level, if not better than myself.

He's naturally very very gifted for the sport.

He's tried to reinvent himself and reinvent what he is doing,

so that he can make a career in this sport. So that it is possible for someone

from his background,

to do what they love and achieve a fully fledged life dream.

Everybody is dealt cards.

It's just whether you get on with it or not.

Parkour is my life. i can't see my life without it at all.
