Use Express Replacement Service for your iPhone
With Express Replacement Service, you get a kit that has your replacement iPhone and everything that you need to send back your original iPhone.
About Express Replacement Service
With Express Replacement Service, Apple sends you a replacement iPhone first — so you don't have to wait for a repair.
After you get your replacement iPhone, send back your original iPhone right away. Apple must receive your original iPhone within ten days after your replacement was shipped.
Your replacement iPhone is covered by a 90-day service warranty or the remainder of your AppleCare plan (or other original product warranty), whichever is longer.

Before you return your original iPhone
Back up your iPhone
Erase your iPhone to delete your personal data and remove it from your Apple Account: In Settings, tap General > Transfer or Reset iPhone, then tap Erase All Content and Settings. You need to enter your Apple Account password to confirm.
Transfer your mobile service to your new iPhone:
If your original iPhone uses a physical SIM card, switch it to your new iPhone or transfer it as an eSIM to your new iPhone.
If your original iPhone uses eSIM, transfer to an eSIM on your new iPhone.
Power down your original iPhone.
Pack your original iPhone
Your Express Replacement Service kit includes everything that you need to pack up and send your original iPhone to Apple — including the smaller white or natural box and larger shipping box that your replacement iPhone arrived in, which you use to pack up your original iPhone and ship it to Apple.
Place your iPhone into the smaller white or natural box. Don't include anything else — such as a phone case, power adaptor, USB cable or other accessory. If you include extra items in the box, they won't be returned.
Put the smaller box into the same larger shipping box that was delivered to you. If there's a battery sticker pasted on the outside of the box, make sure it's not covered by tape or a shipping label.
Ship your original iPhone to Apple
From the email you received when your replacement iPhone was shipped, print the shipping label from the "Repair status" link.
Take your shipping label and your original iPhone (packed in its box) to Australia Post. Find the nearest Australia Post Office
Keep the receipt that Australia Post provides to confirm that you’ve returned your original iPhone.
Apple isn’t responsible for any damage during shipping.
