Hi, I'm from Australia. I found the easiest way to buy, BTC, ETH, LITCOIN, BCC is with Coinbase. They have an app for mobile as well. CONS: You can only buy a maximum of $250 per week.

For larger amounts try coinspot,com.au. You'll pay a higher rate than at exchange prices at both coinbase and coinspot to get in. Research coinspot faq and forums for how to buy in.

I'm happy with coinbase as I have spread my buys over a few weeks and it's simple to use. I trade on Binance.

Once you have coins at Coinspot or Coinbase, you can transfer to an exchange to trade or download to a cold wallet for safe keeping.

Hope that helps
Paul
