The Maria Island Walk guide had planned to ride the Bicentennial National Trail, however had to cancel due to the drought.

After her dream, she changed her plans and made the journey in April to the mouth of the Snowy River in Gippsland, Victoria.

"I don't think it would have occurred to me if I hadn't had that dream," she said.

Accompanying her on the journey were horses Egyptian Arab Mr Richard, 17, and Australian stock horse Mickey, three.

After riding 4485 kilometres in about 235 days, the journey ended at Margaret River in Western Australia on December 6.

"It was about seven-and-a-half months," she said.

"Probably the biggest highlight was being able to spend so much time with my horses. It was just really amazing. I've had horses all my life, but usually you just hang out with them for a couple of hours, a couple of times a week.

"Being able to spend 24 hours a day, month after month with the horses was really beautiful."

She said the trip was "surprisingly easy", with the Nullabor the easiest part due to vehicular support provided by a friend.

"I work in the outdoors so I'm used to the standard things that might be challenging, like sleeping outdoors and cooking," she said.

However, the biggest challenge was the last five weeks coming into Margaret River.

"It started to get really hot. There wasn't that much water, there wasn't that much feed," she said.

"Then my little horse, Richard, got sick. He's totally fine, but he didn't quite finish the trip.

"All in all, it was a fantastic experience and something I will definitely always remember fondly."
