In some languages, like Warluwara, it marks the nouns that accompanies motion. For example, in sentence meaning I'm going with this man the noun man would be in perlative. Others, like Nunggubuyu, also have the retrospective pergressive, which indicates the sense of back with or back among.

In Kamu, the case is marked with the -ba suffix.
