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.
They have a lot of customers outside of Europe and the USA so you shouldn't have a problem. Otherwise, you may take a look at
https://bitcoin.com.au it is the only one I know based in Australia. I have never used it, so make your due diligence before using it, I don't want to be blamed for redirecting you to a shady website. =)
