Over 3000 live music industry members are calling upon the Federal Government for continued financial assistance in an open letter released yesterday.

The live music industry is calling for the JobKeeper wage subsidy to be extended beyond March, as music rights group APRA AMCOS says the industry is only running at 4 per cent capacity. 

"Each time there is another COVID-19 cluster or a quarantine breach, any plans to trade again are halted," the letter reads.

"We are an industry in crisis."

Treasurer Josh Frydenberg says a final decision about JobKeeper is yet to be made, but there should be no expectation it will continue.
