Something I need to add too is that the problem isn't that there is too much land protected, it's that there isn't enough. 500 parks is the consequence of compromising : instead of protecting a huge parcel of land, allowing wildlife and plants to thrive, forests and rivers to recover, state governments usually prefer protecting many small parcels, because farmers want to keep that bit, industrialists want another bit, or that one is too expensive private land to buy back etc... This means that we have isolated pockets that aren't connected to each other. That favors pests (native wildlife has a better chance in a huge isolated wilderness), and isolate populations that can't breed with each other, which favors interbreeding and weaker lineage.
A good example of what not to do is in the South-West of Victoria : isolated pockets such as Lower Glenelg, Mount Richmond, Discovery Bay and Cape Neslon, fringed and separated by huge pine plantations and farmland. On the other end of the state, we have (almost) what should be done with the Croajingolong/Nadgee wilderness, and if there were a nation-wide legislation for national parks, those two could finally be merged into a big national park, in the same way that Alpine, Kosciuszko and Namadgi should be.
And on another matter that lack of merging is true everywhere. Why can't connected national parks be made into a bigger one ? It doesn't cost anything... Deua, Wadbiliga, Budawangs and Morton NPs should be merged into one giant Budawangs NP, why isn't it done ? In the North-West of Victoria, why isn't a huge Mallee National Park being put in motion ? Murray-Sunset and Hattah-Kulkyne could easily be connected, Wyperfeld and Big Desert+Ngarkat in SA already are, it's then only a matter of connecting Wyperfeld and Murray-Sunset with a wildlife corridor. I look at the SW of Australia and wonder why D'entrecastaux, Frankland, Shannon and Walpole-Nornalup aren't a single big park ? It would be easier for everyone.
To get back to the troublesome child, Queensland, they don't have big parks at all. If you look at a google map of Australia, you see significant green portions only in 3 states : SA, VIC and TAS. TAS requires no explanation, it's the model other states should follow. SA followed American regulations on the careful selection of their parks (source : Reader's Digest Wild Australia), allocating vast parcels of land, and Victoria was lucky to have many mallee areas and mountains that weren't really suited for exploitation. If you have a look at NSW, they only protect the coast. In the outback, it's all been about mining, sheep and cattle grazing. Once the pastoral leases expire because everything's been destroyed by logging, grazing, pest and erosion, then they consider declaring it a park (Kinchega, Mungo or Willandra). In Queensland, despite having between 200 and 300 national parks, only 5% (!!!) of their land is protected in reserves and parks, against 10.8 % for the Australian average. This number really shows how having many parks is just a smoke screen for this joke of a state in terms of conservation.
