If you're unfamiliar, Amazon Channels allow you to add streaming channels on top of your existing Prime subscription for a small monthly fee. This lets you avoid paying for bundled channels you don't need.
Here's everything you need to know about Amazon Channels including how to get free trials, available channels and whether it includes Netflix.
Apart from the Australian Open, the offer also gets you access to the French Open (26 May to 9 June) and the Wimbledon Finals (1st to 14 July). This comes on top of the coverage of the US Open, which is included with Prime Video at no extra cost.
