Member for Paterson Meryl Swanson hit out at the Federal Government this week, saying she has received numerous reports of JobKeeper being too confusing and leaving too many people behind.

The Labor MP is calling on the Federal Government to make changes - and quickly.

"Labor has been supportive, responsible and constructive, working with the Government to get much-needed support out the door," she said in a press release. "But being constructive does not mean remaining silent when there are clear gaps that must be filled.

"Many employers can't afford to pay JobKeeper upfront and be reimbursed. These businesses may not be able to participate in the scheme, which will see hundreds, if not thousands of workers miss out on much-needed wage subsidies."

But David Gillespie, National Party MP for the neighbouring electorate of Lyne, rushed to the government's defence, refuting Ms Swanson's criticisms.

"The program will help up to 6 million Australians stay in a jobs," he said. "Already more than half a million businesses have enrolled for JobKeeper ensuring more than 3.3 million employees are kept in a job and off welfare. There are clear fact sheets on the Treasury website and guidance on the ATO website."

He did acknowledge that their had been some frustration, particularly businesses, in accessing bridging finance. "The Treasurer has been working closely with the banks, but we need those turnaround times to improve," he said. "The Government is also providing up to $100,000 to eligible small and medium sized businesses, and not for-profits that employ people, with a minimum payment of $20,000.

"These payments will help cash flow so they can keep operating and retain staff."
