No you're right.
I suspect that, like Ahmed who was picked up by a national branch of Nissan, Thanaroj and Abhinay are being funded by Nissan Thailand and Nissan India. I'd also suspect that Nissan Australia is probably significantly poorer funded than either (population 29m in Australia, 67m in Thailand, 1.2bn in India), so they don't have the money to back you - despite the brand's popularity there. I'd also suspect that the popularity of the brand means they don't need you either, when there's a whole bunch of famous Australian Nissan drivers they can wheel out.
It blows.
