I agree; when coming in the Main Gate everyone either goes directly straight or left through the Lemurs towards the Gorillas ect. Growing Wild as an entire precinct has never gained as much attraction as it probably should; but this can be attributed to its downgrade over time to the point where it now only displays Meerkat and Giant Tortoise (of which can be seen elsewhere in the zoo).
It's not uncommon for me to visit and skip the precinct these days, just feels like a waste of time walking through and all of that space behind could be put to much better use. At the bare minimum, I would introduce Koalas into that former Brush Turkey Aviary to create a little walkthrough there, of which they could share with a species like Quokka; and the former Mara enclosure could also be renovated for a Tasmanian Devil enclosure.
Going further, the current Giant Tortoise enclosure is then more than enough space for a decent sized Little Penguin exhibit; complete with underwater viewing and all.
Overall, it would be a win win. Growing Wild would be able to gain more attention from international visitors and locals too (who would go visit and miss seeing Koalas and Penguins

); and would free up space elsewhere in the zoo, like the whole Wild Sea precinct for redevelopment.
