Operators of a Gold Coast shooting range have been fined a total of $30,000 for asking workers to sign contracts removing their penalty rates.

The Fair Work Ombudsman said operators of the Australian Shooting Academy breached workplace laws by asking employees to sign an Individual Flexibility Arrangement (IFA).

"The IFA removed their entitlement to Modern Award penalty rates for overtime, weekend and public holiday work," Fair Work said in a statement.

"Five of the six employees ultimately signed the IFA."

Fair Work said one of the employees signed the IFA after he was threatened there would be no work for him if he didn't sign.

The Academy was also ordered to pay $7146 compensation to a worker who was given no more work after refusing to sign, the Ombudsman said.

The Academy runs a public indoor shooting range at Centro Surfers Paradise Shopping Centre.
