These are definitively Kingia australis. Kingia leaves are softer and more flexible than the tough sclerophyllous leaves of Xanthorrhoea, because of this there is a subtle difference in the crown shape of Kingia in the way the leaves arch to a higher degree comparable with that of Xanthorrhoea. Xanthorrhoea leaves in the apex tend to be more rigid and are held in a more upright straight fashion. In addition, there are no Xanthorrhoea species that produce the sheen on the leaves of Kingia as the result of the fine hairs on Kingia leaves, as seen here. Xanthorrhoea leaves are glabrous.
@Tapirlord : What do you think? Can I create Diuris sp. Augusta. See: https://keys.lucidcentral.org/keys/v4/wa-orchids/key/wa_orchids/Media/Html/entities/diuris_sp._augusta.htm
