Just reproduced the issue on MacOS. The problem is just with the “ad & tracker blocking” functionality of your Brave ad-blocking shields. It seems to be blocking some CSS which is breaking the styling of the website. (Side note: I suspect some websites purposely do this to break their site for ad-blocking users.)
Temporary solution: As a temporary solution, click your Brave shields (lion icon in the top right corner) and disable the “ad & tracker blocking” (this will only apply to FoxSports.com.au). You can also just disable the shields entirely. You should see the page refresh and come to be styled properly again.
