This only applies to none refresh plans.
If you have a device plan, then you have to pay off the device plan in full at time of cancellation. As thats a Consumer Credit Agreement.
As stated here...
Some of the changes to our out-of-bundle charges and Roaming Limits on Tariffs over 25GB, may mean you have the right to exit your agreement without having to pay an Early Termination Charge. If you choose to exit your agreement and have a related Device Plan you will also have to repay it in full.
