Guys, you have to put it in perspective. Using Wikipedia as a source, Port Elizabeth has a population of 312,392 and Sydney 5,005,400. The Eastern Cape is also one of the poorest provinces in RSA.
If you scale the PE and Sydney populations, a PE crowd of 2,226 equates to 35,700 attending Moore Park.
"Incredible" starts with the attendances at Aussie games and continues with SARU considering Port Elizabeth a sensible place to base a professional rugby franchise. The economics and supporter base was never going to stack up. It won't get substantially better with the Celts albeit a South Africa wide based TV following could potentially rise depending on the success of the Pro14 comp.
If they are relying on gate taking they are in trouble. Inevitably ongoing cash input could be required from SARU or the Govt.
