As of Oct. 5, Australian customers purchasing iPhone, iPad, Apple Watch, Mac, Apple TV, AirPods, HomePod, iPod touch and other eligible Apple devices receive a seven-day complimentary AppleCare+ plan that affords all the trappings of a full subscription.
According to Apple's terms and conditions, the free AppleCare+ service covers two incidents of accidental damage within the seven-day period, with each claim subject to the usual service fees. Also included is express replacement service, priority access to telephone or web-based technical support and battery service.

Worth noting this is only for purchases direct from Apple - online at apple.com/au or at an Apple Retail store.
As Apple are the ones providing AppleCare+ insurance, to absolutely comply with the law, they're not selling it at the same time and making it complimentary.
If you buy from a retailer, like Harvey Norman, Officeworks, JB HiFi etc - as they're not the ones selling AppleCare+ insurance, Apple doesn't need to offer the 'complimentary' coverage and you can buy/pay for AppleCare+ right away after unboxing your Apple device.
