Hi Mate, I am a CryptoLifeCoach here in Sydney. Many of the sites have similar fees but they do not accept AUD. I use coinspot & cryptopia (follow my links). They are great sites for instant buys and trading. Coinspot defiantly add a heavy commission to there coins but they have great service and its simple to use, they use Poli Pay which accepts most of the big banks here in Australia. No trade platform is good to leave coins on. I would highly recommend buying Cobinhood coin (COB) and register with them once they launch in few weeks. Zero trading fees and they offer insurance on any coins you hold with them, no brainer really. Otherwise you need to get MetaMask. I have just started a insta page - check it out for tips and news on coins @cryptolifecoach
