Stamp 2 under graduate scheme and Naturalization?

[treefriend]

Hey Guys,
I was given stamp2 under graduate scheme after graduating. This scheme allowed me to work for 4o years. I am now moved to stamp4.

I am wondering whether this count toward 5 years of residency to make me eligible for Naturalisation?

Thanks
