Generally, numerals precede the noun. At least in the varieties spoken in Katherine and in the Victoria River District, the numeral 'two' is also found following the noun (and it appears that it is prosodically integrated with the noun). In this case it can either be analyzed as a straightforward dual marker, or as a dual marker in an inclusory construction. In the latter case, the combination does not mean e.g. "two X" but "X and someone else". The inclusory interpretation can however also apply to a noun phrase with the nominal 'two' in prenominal position.
