GDAX, Bitfinex, Bitstamp, Cryptopay, Cex, are a few example but it depends on what payment method are you planning to use. Coinbase purchases are by credit cards, right? I think Bitstamp can be used to buy using a card.
Thanks, i can use credit card and bank account for purchases, however are there any crypto markets that are specifically for Australian residents? These exchanges mainly are for European and US residents.
