Greetings all

Just seeking advice on money in Namibia. I'm off to Windhoek in a week, and am unable to get NAD at home in Australia. So trying to figure out the best course of action so that I can grab a taxi from Hosea Kutako International Airport to my hotel in the city (advice seems to be to have some cash on hand for this). Google suggests that Rand is accepted there, so just wondering how widespread the acceptance of Rand is in Windhoek? I have some leftover from a previous trip to South Africa, but don't want to get stuck in a taxi who won't take Rand. Is it accepted pretty much everywhere, or will I actually need to exchange some money for NAD or find a Namibian ATM on arrival? Fully intend to use my card for everything possible, but sometimes cash is needed!

Thanks heaps!
