A workaround: use geometry generator to create buffers around the south pole. The [distance between Degrees of Latitude is ca. 111 km][1]. Use this value and mulitply it, using `array_foreach` to create several grid lines at once, here with an interval of 5 degrees (last number in line 3).

Use this expression:

```
collect_geometries (
	array_foreach(
		generate_series (0,30, 5),
		transform (
			buffer (
				make_point (0,0), 
				111000*@element, 
				200
			),
			'EPSG:3031', 
			'EPSG:4326'
		)
	)
)
```
