Looks a lot like Licuala grandis, but mine don't have big spikes like those. Livistonas generally do. Can't think which one other than L. rotundifolia, but the leaflets are usually a bit more divided than that.
Let us know when you do. I curious to know exactly what it is. Has that "Licuala look" about it, but the only Licualas with spines like that I know of are L. spinosa and L. ramsayi, and their leaves are completely/mostly divided.
