In The Garden: Is this a palm of some description

Hi, trying to identify this plant to
1) know how to care for it, and
2) know what it will be like when mature.

Just moved to our new house.

Any help appreciated.

Cordyline of some sort (not a palm).

 

Thanks Michael, that sets me on the right track - can you tell me how I'd go about narrowing down the type?

 

A variegated form of C. australis.
