Free Internode SIM for 6 months with no obligation to continue after the free period and no fees for cancelling the service. No cost to port your number from another provider either.
The SIM includes $450 of calls & text and 1.5GB data, plus 150GB social media data per month. Rates seem reasonable too, so the cap won't be used up by crazy call/text rates. Also, Internode SIMs use the Optus network.
Requires signup to an Internode service or recontracting for existing Internode customers and you may need to call Internode (13 NODE) to claim the offer, although I was automatically prompted to add the SIM when doing my order online.
By the sounds of "The Summer SIM Campaign includes the $10 SIM purchase charge, the $5 SIM delivery charge" I think the delivery is free too.
This deal is compatible with the Internode Naked 150 Special, which is still running: http://www.ozbargain.com.au/node/69911
