South Africa’s casinos enjoyed healthy growth in 2016 but they continue to claim their biggest fear is the rise of online gambling.

This week saw the release of the latest Casino Association of South Africa (CASA) annual Survey of Casino Entertainment. CASA, whose members include Tsogo Sun, Sun International, Peermont Global and Caesars Entertainment’s London Clubs International brand, represents 36 of the country’s 38 casinos.

According to CASA, gross gambling revenue totaled R18.2b (US $1.35b) in the 2015-16 financial year, up 6.7% from last year’s figure and better than last year’s 3.4% growth rate. CASA members paid R4.9b in gaming taxes in 2015-16, representing 27% of their gaming revenue.

Gauteng remains the provincial casino revenue star, as its seven casinos generated nearly R7.5b, more than twice the R3.4b of its five competitors in KwaZulu-Natal. The Western Cape ranked third with R2.8b while the North West was well back at R1.35b.
