The Southern Cross has no classical astrology
Not every figure has an astrological lineage. The Southern Cross is a clear case: it became a constellation of its own only around 1600, and this site has found no sourced astrological reading of it.
Why there is nothing here
In Ptolemy's day the Cross was the centaur's hind legs; as a figure it has no entry in his astrology.
Ptolemy catalogued these stars, but as the hind legs of the centaur (opens in a new tab). Crux was first listed as a separate constellation in 1603, so the classical astrology this site reports never treated it as a figure.
Tetrabiblos I.9 (opens in a new tab) compares the bright stars of the centaur's horse-body with Venus and Jupiter, but does not say which stars it means, and this page does not stretch that line to cover the Cross. This site has found no other sourced astrological lineage for it, and would rather say so than invent one.

What the Cross does mean
Its meanings are practical and cultural: a pointer to the south, and part of the Emu in the Sky.
Navigators were using the cross as a pointer to the south celestial pole (opens in a new tab) by the early sixteenth century, and NASA (opens in a new tab) still names it as a way to find due south.
For Gamilaraay and Euahlayi people, the dark Coalsack beside it is the head of Gawarrgay, the Emu in the Sky (opens in a new tab). Historical beliefs has that account.
