Well if you actually want to play sc2, why the **** would you even think about getting optus?
Also if you just want ADSL there will not be any clash. but optus won't connect their ADSL plan to a telstra phone line and they're probably bundled, so you'll probably have to go with telstra ADSL if you really insist on getting 2 plans.
Easy champ, i'm international and haven't been familiar with any ISP in Australia yet. Neither do I have any idea if there is any affordable bundle for me in the large market of 'internet bundle'. But i'm still thankful for your answer, I'll look right into any plan offered without hesitation of interrupting the other couple's internet
