The 27-year-old T38 javelin thrower spent more than an hour on the phone with Olympic bronze medalist, and training partner, Kelsey-Lee Barber and his coach Mike Barber, discussing every detail before he competes in his second Paralympics.

Sawyer said the fellow Canberrans were a huge help with their experience from mere weeks ago in Olympic Stadium.

"We went over every detail that I could possibly think of, and what I didn't think of, they had thought of to share with me. There was so much on the list, anything from weather, to travel, to things to do throughout the actual comp and warm up, all that type of stuff, and it was actually ridiculously helpful," he said.

"I've been able to share that with people here who are also throwing and what not, that will share a pretty similar experience ... so they've also got a bit of a leg up as well.

"She was a huge help, because some of the stuff that she mentioned I didn't even think of."

In 2016 in Rio, Sawyer finished fifth, before the following year he took home a gold medal at the World Championships in London with a world record throw of 52.96m.

He aims to get back to the podium on Friday, and said the Australian team's training in Cairns had helped with the heat and humidity in Japan. However it was a little warmer than Canberra.

"For me, I think the biggest thing is trying to get back on the podium, I've been there before and just dropped off in the past couple of years," Sawyer said.

"So it would be nice to be back up in that area and whatever happens, happens. I'm just excited just to go out there and see what I can do, and be happy with what result I get, more to the point.

"It's probably more about having this one for myself rather than worrying about other people's expectations or what other people think is going to happen, I think I'm just kind of in the mindset of just going out there and actually competing and being there for it, rather than the worrying about where I'm going to place or all that type of stuff."

Throwing for himself, without paying attention to outside expectations, has been a feature in his growth as an athlete.

Sawyer said he learnt something from every Australian team he was in, and after seven he had learnt to focus on his own expectations and taking in each moment as it came.

"I looked back and just saw that I wasn't really taking the whole moment in. I was just letting it go by and worrying about certain things and certain aspects," he said.

"So I really said to myself for this one, I really just want to go out there and enjoy it, enjoy the moment, and to try and throw as far as I've thrown before. So, if I can do that, I'll be happy."
