What Hydriastele species are native to Australia

I have a very nice Hydriastele sp I grew from seeds sent to me by a palm lover in Australia about 4 years ago before obtaining seeds from there became nigh on impossible. Could anyone in Australia tell me what Hydriastele are native to there? I know a number of genera, i.e., Gulubia, Siphokentia etc. were subsumed into Hydriastele. I have the impression the whole genus is quite tropical but I’m not sure. I would love to plant this guy as a replacement palm in our decimated jungle and I actually have two Hydriastele dransfieldii planted that survived Hurricane Ian and this past winter (ultimate low 41.2F = 5C). My oldest dransfieldii has survived the past 3 winters outdoors so not all species melt in morning chill.

I will take photos tomorrow. The palm is in a 5-7g pot, about 3-4’ tall above the soil. I see no sign of clustering and assume it is solitary. The jungle where I will plant it faces south and sits on a ridge overlooking our 80’ wide freshwater canal, which will be 6-8’ deep going into winter. I expect some temp moderation on cold nights in Dec./Jan. The winter sun in SWFL is still fairly strong even at its nadir.
