An unapproved private market at Palm-Beach Currumbin High School looks like being given the heave-ho.

Council's Planning Committee on Monday recomended their application to extend trading hours to be rejected, with concerns about parking.

Commitee Chair, Councillor Ted Shepherd said the business was currently operating 6-11am every Saturday without approval.

A show cause notice was issued in Februaru last year, which has prompted the application to open Friday night - as well as Saturday and Sunday.

Cr Shepherd said there were already parking problems with the existing markets, let alone an extended version.

"Even the applicant’s own traffic consultants conducted a Saturday morning traffic survey and identified 61 illegally parked vehicles within a 200 metre radius of the markets."

He said the operators had made no provision for on-site parking for market patrons.

“At Council’s urging, the applicants contact the school to see if they would provide parking within their grounds but the school rejected the request."

If the committee’s recommendation is adopted on Monday, Council will take appropriate action to have the unapproved markets closed down.
