Viv/palu size dilemma

[Calayvie]

Hi. I'm not sure if this is the right place for this post, or the 'frog' sub forum.

I'm having a moral dilemma that has been at the back of my mind for a while now.
Is my tank big enough for the frog I want?

Which is a eastern banjo frog, Limnodynastes dumerilii, which is a burrowing frog common in Australia.

The aquarium tank is, in inches,
36l x14w x 18h, and its a burrowing frog that could grow as big as 8.5cm / 3.5in.
I've planned a water section for about 11inch in length. That leaves about 2ft for land space, I plan on limited plants (a climber for the back wall + maybe a couple more on the edges, depending on how they handle be trampled).

I don't know what height the adult frog can jump.

And I'm really worried I'm going to hate myself for keeping such a large frog in a smallish tank.

I don't want to keep a creature if I can't make it happy, that's a failure and defeats the purpose.

I do want to keep a frog that we have raised from an egg, and I do want to support my 4yo's love for all creatures (especially frogs, reptiles and creepy crawlies). So I'm totally torn between keeping a frog because my son would love it (I want to too, but I can let it go), and thinking this species may not be suited for us or the tank we have, at the least.

What do you all think?
