Thanks to djshitu for pointing out that the 2m cables are now discounted! 1m cables are still available for ~$1.51 shipped if you're after something smaller, more info available in this post. Price inclusive of GST.
Cables contain the required 56Kohm resistor, so are safe (I confirmed this here.) I have plenty of these and am very happy with the quality (quite thick cable, gold-plated connectors).
Plenty of other cables in this price range on JoyBuy, such as:
Romoss CB21 1M Type-C/Micro-USB to USB cable - ~$1.09 USD (~$1.47 AUD) - Recommended by Butt Scratcher.
HSC X22 1M Micro-USB/Lightning to USB cable - ~$1.41 USD (~$1.91 AUD) - cable seems very durable, thick and braided. Have used with my iPad Air and iPhone 5s for the past month with no worries. Obviously not MFi certified at this price so buy at your own risk!
EDIT: Out of stock - 1M is still available though.
Dupe?
