There is a call for the security industry to dramatically improve its compliance with workplace relations laws after underpayments locally and nationally.
The Fair Work Ombudsman has recovered $17,000 for 36 workers at a Wagga Wagga security firm and $5,000 for three workers at a business in Deniliquin.
It follows a national audit of businesses providing alarm monitoring services and security at events and airports.
The Fair Work Ombudsman says more than $450,000 in back pay is being recovered in the national audit.
It was sparked by concerns about the high number of complaints and prosecutions the security industry was generating.
Of 83 New South Wales security companies audited, the Ombudsman says 55 of them, or 66 per cent, were non-compliant.
