Hi I have limited experience having only taken part in 1 ICO previous to this. But you will need to get myetherwallet it's a simple process of adding that extension to google chrome if you are paying with ETH . Once you've emailed Discovery Capital they will send you further info. They have an option of just transferring AUD to USD to them and they can even store your tokens for an annual fee if you like. All that info will be in the email you receive. I would suggest getting the myetherwallet and just buy a small amount of ETH from an exchange and then transfer it to you myetherwallet, just so you get the hang of the process before sending large amounts of currency. If you google 'how to send crypto or YouTube it there is heaps of easy to follow videos. I'm a computer gumby and I eventually got my head around it (sort of) so I'm sure you'll be fine.
