Scrutiny of Australia's charity sector is intensifying, with another 182 organisations removed from the Federal Government's official register.

The National Charities and Not-For Profits Commission (ACNC), which regulates the sector, revoked the organisations' official charitable status to "ensure only active and compliant" charities were listed.

ACNC commissioner Susan Pascoe said the decision was made after the 182 charities failed to complete their 2013 and 2014 annual information statements.

"We conduct regular reviews of the charities registered with the ACNC to ensure only those that meet their obligations maintain their registration status and are able to access Commonwealth charity tax concessions," Ms Pascoe said.

Ms Pascoe said the decision to revoke charitable status came despite "multiple reminders" for the organisations to prove their eligibility.

"It is important to note that this group represented only a very small minority of charities," she said.

"The vast majority of registered charities are accountable and transparent and meet their obligations."

Ms Pascoe said information about the registration of charities provided important information to donors, volunteers and agencies or individuals providing grants.

An ACNC report released earlier this month showed there were 54,000 charities in Australia in 2014.

It is estimated the charitable sector employs 9.7 per cent of the Australian workforce, with a combined worth of $103 billion.

The extra heat on the regulation of the charitable sector follows revelations that only 16 cents in every dollar donated to the Shane Warne Foundation went to care for sick and unprivileged children.
