I recently find this St Remio coffee pods in Coles (example link from OW) and they say K-fee and Caffitaly compatible pods.

A quick search online seems indicate that pods made for Aldi's K-fee Expressi and Caffitaly system are compatible? Coles starts selling compatible pods for Aldi coffee machine. I would like to hear real experience if anyone wants to share.
Similar but not 100%. Just minor dimension differences.
