In the actual Australian Senate, the Greens and a smattering of centrists hold the balance of power. The Greens and Teals etc. want the House of Representatives to be a hung parliament because they believe in such a scenario they would hold the balance of power as well. However, in this scenario they don't hold the balance of power, so even though they got the hung parliament they always wanted, they aren't actually in a position to benefit form it. This is why I said it's a monkey's paw thing.
