The Eastern Cape is the province which showed the biggest improvement in its audit outcomes in the past financial year.
This emerged Wednesday during the release of Auditor General Kimi Makwetu's annual report on national and provincial audit outcomes.
In the Eastern Cape, 36% of audits were better than last year, followed by Kwazulu Natal with an improvement of 26% and Gauteng at 14%.
The province with the highest number of auditees with clean audit opinions in 2015-16 was the Western Cape at 79% followed by Gauteng at 60%.
Meanwhile, the DA said it will be calling for the Standing Committee on Public Accounts (SCOPA) to thoroughly investigate and then ensure accountability for every cent lost to irregular, fruitless and wasteful expenditure.
Makwetu revealed that irregular expenditure increased by 80% from the previous year, to R46 billion.
Makwetu said six auditees were responsible for just over 50% (R23 billion) of the irregular expenditure in 2015/16.
These include the Passenger Rail Agency of SA (Prasa)‚ KwaZulu-Natal and Mpumalanga Health Departments‚ Transport and Human Settlements Departments in Gauteng and the Department of Water and Sanitation.
