The Wamboin teenager will head over to New Zealand in January to compete in the Australia verse New Zealand Intermediate Mixed Test Series.

McInnes is hoping they'll be able to chalk up a few wins against their rivals but it won't be without its challenges. He has only played alongside one of his fellow squad members while the remaining seven that were picked are spread across Australia.

Not only that, but McInnes will have no choice in his horse, only being able to ride the horses supplied overseas. But the recent Braidwood High School graduate remains upbeat.

"It's not too bad because everyone can already play quite well. I've been in that situation before where we haven't met and played together before and it turned out pretty well," he said.

"You just have to have lots of communication, there's a lot of talking to each other and working things out. You just have to work with whichever horse they give you."

Polocrosse is a combination of polo and lacrosse. Each rider uses a racquet to help move a rubber ball along the field with the main objective to get the ball into the opposing team's goal.

McInnes regularly plays in the number one position throwing goals for Braidwood, NSW and also belongs to the Ballan Club in Victoria.

This year he has played in several carnivals travelling all across the country to Darwin, Victoria and Queensland.

"It's a pretty rough sport - it's hard and pretty fast, it's tough out there. You've got to be able to have good racket skills and ride a horse pretty well. I've had my arms cut, fingers cut open and been hit in the head. So, that's a challenge getting through all that," he said.

"It's just flat out for six minutes but I keep pretty calm when I play. I just cruise around and I don't really get flustered or anything. I've always just sort of been like that when I play."

Perhaps McInnes' talent is a result of nature and nurture as his family run horses on their rural property.

After years of competing in mounted games, McInnes took up Polocrosse just two years ago. His father and older sister, Amelia is also involved in the sport.

When McInnes isn't training, he works on creating bespoke equestrian items like beaded and leather belts, spur straps, bridle and breastplates for the online business he recently started with his sister called Mil and Mark Australia.

Ultimately, McInnes said he would like to qualify for the Mens World Cup side for the polocrosse world cup but until then he'll be training for the big game.

"I'll be doing lots of riding and just practising at home with the racquet before I go over," he said.
