It's a representation of this country, you'll see the Lachlan River and Lake Forbes, but it's also a tribute to the people who have established the family healing centre now located in the former Jemalong Regional Education Centre.

Mr Mckenzie visited Forbes earlier to paint one of the walls inside the centre, he returned last week inspired.

"My aim and vision was to pay respect to these wonderful ladies," the artist said as he put the finishing touches on the work last Thursday afternoon.

"It's a reflection on what Donna (Bliss) and Dee (Anderson) have done over the past 18 years.

"Yoorana Gunya is an amazing place, with a very welcoming vibe."

The mural's vibrant colours are there to brighten your day, but they also tell the story of the country.

"When we, as Aboriginal people, say country we mean all-compassing," Mr Mckenzie explained.

"It's the land, the waterways, the animals, the plants, the people."

The mural shows people on a journey, and gathering, and the artist was eager to communicate the centre is for all people.

The mural contains the Lachlan River and the Lake, and represents the changing environments and seasons people face.

"Sometimes we feel parched and drained, sometimes full and fast-flowing and we feel overwhelmed," Mr Mckenzie wrote.

"The many bends, twists, turns and barriers below that can't be seen must be maneuvered through with care and some parts, still calm and even flowing, we feel at peace.

"This is the journey of life in this mural.

"Making good choices, thinking of others, creating balance and then seeing the burst of opportunity this brings to light."

The vibrant piece, which took shape over four days, celebrates a bright future.

McMckenzie thanked everyone at Yoorana Gunya for their help and support, and all the community members who had stopped to chat and get photos with him.

He's been thrilled by the response to the mural both locally and online.
