  The phase diagram of the planar t--J model at small hole doping is
investigated by finite size scaling of exact diagonalisation data of NXN
clusters (up to 26). Hole-droplet binding energies, compressibility and static
spin and charge correlations are calculated. Short range antiferromagnetic
correlations can produce attractive forces between holes leading to a very rich
phase diagram including a liquid of d-wave hole pairs (for $J/t\gtrsim 0.2$), a
liquid of hole droplets (quartets) for larger J/t ratios ($J/t\gtrsim 0.5$)
and, at even larger coupling J/t, an instability towards phase separation.
