Sundrop Farms has commenced the construction of their 20-hectare greenhouse, solar energy and desalination facility in Port Augusta.
Construction contractors have been leveling the soil around the site for the greenhouses and solar panels since December.
Sundrop CEO, Philipp Saumweber, said the greenhouses would be constructed by the end of this year with the building process scheduled to start by May.
"Then they'll be up and running by the middle of 2016," Mr Saumweber said.
"It'll be a total of four blocks, at five hectares each."
Half of the site will be set up for the solar panel system which will power the desalination component of the watering system.
Once construction is completed the farm will be approximately one hundred times the size of the original test site.
The completed site will also see around 150 people gaining employment, with applications open to anyone via the Sundrop Farms website.
Sundrop is hoping to employ as many locals as possibly by providing specialised training.
Mr Saumweber said training for the positions will be starting in the next few weeks so now is a good time to apply.
Sundrop will produce 15,000 tonnes of tomatoes a year, which will be sold through Coles supermarkets.
