I just noticed on the DickSmith's website, Telstra $30 Starter Kit Nano SIM down to $10.
Great offer if you just got the new iPhone 5 or iPad Mini
Unsure when the offer ends
Click & Collect Available
Deal doesn't seem to include Standard and Micro SIMs but as suggested by @kspec, you can use an adapter.
EDIT: Due to popular demand for this product, delivery is no longer available, however you can still buy in store, but check store stock first to save time, just incase it's not available at your local store.
