There's more than meets the eye to this great photo of four emus in Dhilba Guuranda-Innes National Park on South Australia's Yorke Peninsula.

The part you can't see?

Well, you can actually see it, but you might not realise that the stretch of land in the background is Kangaroo Island.

So with kangaroos and emus, we've basically got ourselves the Australian Coat of Arms here folks, which – fun facts! – is officially called the Commonwealth Coat of Arms and came into use in 1912.

The rainbow in the middle? Feel free to read whatever symbolism you like into that, but in pure weather terms, it's indicative of the fact that there was a fair amount of instability and moisture in South Australia on Wednesday.

Rain fell across much of the state, with heavy falls in some areas. For example Port Augusta had 39.6 mm to 9 am this morning, much of it in a short afternoon burst that caused flash flooding and also brought hail.

Port Augusta has been hit with flash-flooding and severe thunderstorms, with the heavy rain causing a Woolworths supermarket roof to collapse. #7NEWS https://t.co/GFsWosyM4P

To put yesterday's 39.6 mm in perspective:

• Port Augusta only saw 18.2 mm of rainfall for the whole of winter 2022, but copped 18.8 mm between 4 pm and 4:23 pm yesterday. So more rain fell in 23 minutes than the whole of winter!
• Port Augusta's average September rainfall is 17.6 mm.
• Port Augusta's average annual rainfall is 214.8 mm.

Meanwhile Adelaide saw 7 mm from this system, although there were heavier falls in the Adelaide Hills, while multiple locations in forecast districts further north like the Murraylands and Riverland, and the Flinders and Mid North, saw much-needed falls in excess of 20 mm.

The rain has now moved its way eastwards, with a huge rainband extending from southern Qld to northern Tasmania. Good falls of rain should be reported across an extremely wide chunk of eastern Australia today.

As for the Yorke Peninsula emus, we're not sure where they got to, but they probably enjoyed the soaking as emus love to wash their feathers in fresh water and indeed are even keen swimmers at times!
