buying btc is easy
localbitcoins.com is good kinda like ebay with trust rating
coinjar.com is straight forward, they are going really well, woudn't mind a slice of their action
if you are capable of buying shares online you can buy btc
as you are aware it's volatile so you're at the speccy end of the market
I've had more success with it than some of the dodgy asx listings I've thrown money at
