Probably need to supply your own cable (it comes with 30 pin which is useless for most) but for those like me who already own plenty of cables, this is a good price for a 2.4A adapter that should be reliable and meet all Australian electrical standards.
Plenty of stock at most stores (probably because it was still tagged at $40 at my store at least).
Also with lightning cable at $13.49: http://www.dicksmith.com.au/chargers/ds-wall-charger-lightni…

I would suggest the $15 dollar one from Ikea if you want something local.
Review for EU version.

Personally, I would avoid any generic chargers such as the DSE branded one. You just have no idea what is in there. Unless they have been properly reviewed, like the IKEA one above.
