Following are circles of latitude between the 25th parallel south and the 30th parallel south:

26th parallel south

The 26th parallel south latitude is a circle of latitude that is 26 degrees south of Earth's equatorial plane. It crosses the Atlantic Ocean, Africa, the Indian Ocean, Australia, the Pacific Ocean and South America.

Australia

In Australia, the northernmost border of South Australia, and the southernmost border of the Northern Territory are defined by 26° south.

Additionally, 26° south also defines an approximately 127 metre section of the Western Australia/Northern Territory border at Surveyor Generals Corner due to inaccuracies in the 1920s for fixing positions under constraints of available technology.

The parallel also defines part of the Queensland and South Australia border between the 138th and 141st meridians east.

Around the world Starting at the Prime Meridian and heading eastwards, the parallel 26° south passes through:

30th parallel south

The 30th parallel south is a circle of latitude that is 30 degrees south of the Earth's equator. It stands one-third of the way between the equator and the South Pole and crosses Africa, the Indian Ocean, Australia, the Pacific Ocean, South America and the Atlantic Ocean.

If Earth were a perfect sphere, this would be the parallel that divides the Southern Hemisphere's area in half. However due to Earth's oblateness, the true latitude that does so lies a little bit to the north.

At this latitude the sun is visible for 14 hours, 5 minutes during the summer solstice and 10 hours, 13 minutes during the winter solstice. At solar noon on 21 December, the sun is at 83.83 degrees up in the sky and at 36.17 degrees on 21 June.

Around the world Starting at the Prime Meridian and heading eastwards, the parallel 30° south passes through:
