Cheap and cheerful (maybe) Qwerty phone at Ritchies supermarkets this week, certainly available in Victoria, not sure about the other states.
It's a basic 2G-only phone but has a few nifty features such as expandable SD card slot, threaded texts, fake call feature and the QWERTY keyboard.
Also as a bonus you get a free backpack.
It's with Vodafone (boo) but perhaps can be unlocked at home?
Anyway overall for $14.50 you can't go too far wrong for a spare/holiday/pub phone.
**Note I couldn't find this listed on their site but it is part of a 141st birthday flyer delivered this week.
fake call feature… haha, worth it for that alone
