For those unfamiliar with Monty Python's Flying Circus, "The Golden Age of Ballooning" is the first episode of the fourth and final season, notable for being the first episode without John Cleese.[0]

No idea if 9front is intentionally referring to this.

It is one of my favorite episodes too! It’s got such a different feel than the rest of the series, it really sticks out conceptually. I find myself thinking of it from time to time.

Given the general tone of 9front, I would say the reference is intentional.

Yes.
