Tony Sharley

Founder and Guide

Tony grew up in Renmark where his love for this river first started.

When asked how long it took him to create Murray River Walk, Tony replies, "about 60 years." With a background in environmental science, Tony's passion for the river is undeniable. His belief that anyone who saw, heard, and understood the river as he does would share his enthusiasm inspired him to create the immersive experiences we share today.

Sophie Hoffmann


Growing up in Renmark, Sophie has fond memories of being in the bush and river as a child, particularly on horseback.

She has a background in science focused on plant and soil biology but loves learning everything about the environment and is often getting out in the field to help facilitate citizen science.

She has a strong connection to water, and loves a swim in the Murray on a sunny day, even in winter!

Sam - Murray River Trails Guide

Sam Sharley

Sales and Marketing Manager/Guide

Sam grew up in Renmark and spent his holidays camping or houseboating on the river. The health of the Murray Darling Basin was standard dinner table conversation in the Sharley house growing up, and he recalls being particularly impressed on one occasion when his father managed to weave an update on the flow in the Murray into a speech at his brother's wedding.

He joined the guiding team in 2019 and while he mostly fields booking enquiries for the tours these days, he jumps at the chance to get back out in the field.

Hailing locally from Barmera, Kayla has a passion for local food, footy and the Murray River.

When she's not guiding, Kayla plays an instrumental part in developing the local women's football league.

Cathy Ross


Cathy has made a ‘river change’ to live in the Riverland and taken on a new adventure as a boat host. The first thing you'll notice about Cathy is her love of life. It radiates from her and is as infectious as her laugh! She loves to provide guests a holistic experience from tasting great Riverland food and wine, to sharing stories around an open fire on the riverbank.

Her motto is ‘life is not a rehearsal’.


The crew were so incredibly skilled and knowledgeable and everything so streamlined. They work so tirelessly so that we could have an incredible holiday as well as learning experience. Really appreciated all their efforts.
