Hi All, Just need some help with this..

I'll be travelling to australia for a friend's wedding and it's gonna be my 1st time there. so i applied a visa through a travel agent, i've gotten back a slip that says this. "VISA/ETA ON DISPLAY CANNOT BE REPLACED BY ETA REQUESTED" at the bottom of my visa.

Really confused if i've gotten my visa approved or not, but my travel agent say it's fine to just proceed. just need some confirmation about this. can anyone help? thanks!
