Yes I think it looks very similar to sago palm. I think it must be from the same family. It dosen't have any spikes on the base of the stems or center flower crown like a sago palm. I will try and get a better photo.
G'day gilgold, hows hot old Perth going? I think you might have either a Lepidozamia or Macrozamia. There are a few cycad resident experts on here that may be able to help... With the slow growth rate it may be one of the 2 above as they are usually slow growers. Ed
I did some research on the internet with the clues you gave me and think it might be Macrozamia macdonnellii?
