Yeah, the fact that a politician has backflipped on a prior commitment isn't news, and it doesn't change the legalities of what happened.
It is lip service. The media were spinning the repurposing of the tourism grant as an environmental catastrophe for Koalas, and making Qgov look bad - So she makes a public statement that has no legal or other obligation that makes her look better (but will no doubt still be dug up by the LNP at the next state election) and in a few days the story is buried by newer news, and everyone forgets about it again (until the election).
Just remember - come election time, it was a tourism grant, and it was used to increase tourism.
Also remember - a lot of projects have been impacted by covid (like Leviathan, apparently) and some things got cancelled altogether (I just discovered Qantas permanently stopped their valet service at brisbane airport, for example).
Projects have been cancelled all over the world as a result of this pandemic, and lots of the funding for those projects has been diverted to other more useful endeavours to keep people in jobs, and to keep essential services running. The point is, the world has changed, and if you're going to sit and insist that someone should do something really expensive because they said they would prior to the pandemic - and you don't realise that practically all bets were off in the first lockdown, you're either a fool, or you have an ulterior motive.
