The Woonona festival stage designer and producer has been making extravagant creations for events, film and television for years, but for the first time he has designed a Robot SPACELand for Vivid Sydney 2019. On Friday and Saturday nights fireworks punctuate the story.

"We created three large new large works - the largest of which is called Evolution Island and is on a 20 by 10 metre barge and weighs 39 tonnes," Bestman said.

"There's a 15-metre tall car-crushing robot called Ecobot and she picks up wrecked cars, then crushes them into these usable car bails.

"Then there's TerraScorp - a "terraforming" robot who uses a rotary hoe to cut channels in martian soil, and then uses her tail to plant plants off her back, into the soil, to oxygenate alien atmospheres.

"Then there is Tree 1.0 - which is like a beautiful vignette about the progressions of the stages of life ... and ends with this robot called Liftobot who is, like, picking fruits from the Tree of Knowledge."

Although the amazing mechatronic creations have resemblances to different comic book characters or scenarios, Bestman explained there were no definitive influences or role models for the SPACEland.

"What this is really to do with is a mind of an eight-year-old child," he said.

"We like to keep our art fun and top-line and not too heavy.

"We focus on making our works big because that immediately has an impact - it's big, it's light-hearted, it's unusual and it generates some sort of emotional response."

The robots and their mechanical world were made from various recycled and reclaimed materials sourced from a five kilometre radius of Bestman's Marrickville production facility.

Some visitors to Vivid may comprehend the environmental messages while others may simply enjoy the light show and accompanying soundtrack by Peewee Ferris.

"There's also [themes] in there on the mass turnover of consumerism within our society, concepts around reuse and sustainability," Bestman said.

"We're not into ramming things down people's throats. That is the concept, take from it what you will."

Vivid Sydney: Light, Music and Ideas Festival is a free event around Sydney and runs until June 15.
