Where is the location for Cabin Filter

[wagga_ria]

HI All

I have a 2011 Ford Fiesta WP.

I thought of changing the cabin filter myself.
I found instruction on youtube.
Looks simple enough.

But when I removed the panelsn(tried both sides), I could not find the cover to the filter, as what were shown in youtube. Tried both sides but I can't find the plastic cover.

I know the youtube were of British and American version of Fiesta.
But I don't think they would be different from Australian version.

Any help appreciated.
