Terra is a woman on a mission.

When the walk is complete, she will be the first woman to walk unassisted around Australia.

The Bonny Hills resident is currently home for a few days before heading back out to complete the trek by May.

Having spent 123 weeks over the last four years walking around Australia, Ms Lalirra admits she is probably the slowest solo walker in the world.

“I have spent the last four years walking more than 16,000kms around Australia taking in some of the most isolated and regional places, but more importantly taking in the most gorgeous landscapes imaginable,” Ms Lalirra said.

“I have been very privileged to be able to have some of the experiences I have had.

“I have walked through every state and territory and have had some very special moments out in the very middle of nowhere.”

Terra said many long days walking alone made meeting new and remarkable people the highlight of her journey.

“While I am walking I do run into people in towns and remote communities who have welcomed me with open arms,” she said.

“Walking across the top of Australia I was welcomed into First Nation communities who allowed me to experience their way of life and shared some of their Dreamtime stories which was unbelievable.

“When I would meet people along the way I would get a recommendation to visit certain places and I made it a point to visit as many places as possible, especially if they came highly recommended by locals.

“I did this because on my journey, I never know if it will be the first or last time I would visit so I take every opportunity.

“You can travel your whole life and not see all of Australia, so I am very aware of trying to experience as many new, weird and wonderful things as possible along the way.”

She said that over her walking journey she has learnt a lot about herself.

“Most people who cross the Nullarbor say that there is nothing to see but I wholeheartedly disagree.

“When you drive that may be the case, but it took me six weeks to cross it and it was just a really magical experience.

“Standing in isolation, while the sun rises, and the birds are chirping all around you is just something so extraordinary and something I will never forget.

“It is a full sensory experience, the sights, smells, sounds and feelings are just like nothing else.

“I think it is the little things that spark memories and transport you back to a different time.”

She also said that walking around the country gave her plenty of time to collect her thoughts as well as see vastly different landscapes.

“My favourite state I walked in has to be Tasmania. Most people walk from one side to another but I actually walked around the edge which was pretty great.

“But my favourite walk has to be on the Mid North Coast, there is nothing like walking at home.”
