It will operate in the Newcastle Street car parking area every Sunday, from 7.30am to noon.
De Williams, of Oxford Street boutique Atlas Divine, was one of several locals to lavish praise on the proposal at the last council meeting.
‘A farmers market would bring more people into Leederville on a quiet day, which would be good for my business,’ she said.
Jeff Bullen, also of Atlas Divine and Leederville Connect Chairman, said that after seeing the success of the Kyilla Community Farmers Market, he believed a similar venture in Leederville would work.
He said the market had brought community spirit to North Perth, not just a business opportunity.
Others said the venture was essential because their choice of fresh produce in the suburb was limited.
Leederville resident Mike said residents either had to shop at IGA or travel outside the area, to places such as Subiaco, for such goods.
Councillors extended the original six-month trial to a year to give the market a fair run.
A maximum of 40 stalls will operate at any one time.
