For Qld I find that Qld Globe offers a lot of info, you can download the abandoned mine site info and it will overlay on the area you are looking at, open 'Land Boundaries' and click on both boundaries and labels and it'll provide a small "i" on areas within specific boundaries, when you click on the "i" symbol it will provide the lease details which you can then Google so you can discover who holds the lease, lease type, contact details, duration etc. Once you start delving into the overall functionality you'll get access to a stack of info.
Using the "Tenures" section and you can select the different tenure types, also gives GPS coordinates of the mouse arrow in the bottom right of the screen.
When you combine this with historic info from Gold & Ghosts, it becomes a powerful tool.
There is a new version out which I haven't tried yet, still using the older version as an add on the Google maps.
