"I never thought about going to the Paralympics or a World Championship before this," Morrison said.

"I've always done sports and to discover Paralympic sport was kind of a lifesaver for me.

"Finding new sports like this is just awesome."

Morrison was affected by transverse myelitis, a neurological condition which affects the spine, only three years ago, which left her with significantly limited mobility.

"I've learned so many things from all of this, and even if I could get up and walk away, I wouldn't walk away from all of the lessons that have come from this," she said.

Other highlights included David Prince and Jarryd Wallace battling down the homestretch with a strong headwind in the T43/44 200 metres.
