Other villages in the municipality included Kilsund, Narestø, Saltrød, Brekka, Strengereid, Vatnebu, and Sagene.

The municipality consisted of the mainland area to the north and northeast of the town of Arendal plus the islands of Flostaøya and Tverrdalsøya.

The predecessor municipality of Austre Moland had the prefix austre (which means "eastern") which was added to differentiate the place from Vestre Moland which was located a little further south along the coast of Norway, but since that municipality was dissolved, the prefix here was no longer needed.

The official blazon is "Azure, a double chevron argent" (Norwegian: I blått en sølv dobbeltsparre).

The double chevron has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

The blue color in the field symbolizes the importance of the sea for this municipality which had a long and rugged coastline.
