That's the easy-to-use-maps.
There's also the aus-wide https://nationalmap.gov.au where you get basic satellite maps with the option to add various datasets and even daily maps from Landsat 2A
There's also ELVIS foundation spatial data https://elevation.fsdf.org.au
There's don't really cover hiking trails that much, etc. There's more general purpose mapping applications.
It's also possible to find various topographic maps in static form somewhere on the government sites.
Councils are the ones that provide the hiking trails, etc. so it depends on the locality. The Northern Beaches council for example provides an interactive trails map, but most have static maps.
Btw: the URL for Six maps is: https://maps.six.nsw.gov.au/
Not sure if it was changed but it took me a few tries to find the right permutation
How do you view daily maps from Landsat 2A? I couldn't find it in the options on nationalmap.gov.au
Planning maps are usually unfortunately only held by the responsible subjects (towns and larger administrative blocks), so there's no one map or one format. Most of these maps are at least published in some viewable capacity, though, from what I can tell.
The debate is what 'free' means :)
I think some of the questions about what 'free' of charge mean are answered below in the frequently asked questions section.

I also use Gaia GPS as a planning tool. Fiddle with routes on the laptop, then load the relevant map squares on the phone for offline use. It has the NatGeo maps, plus several other sources, available for overlay. With this, my NatGeo paper maps largely become backups.
I guess the paper will be out of date, I'm not sure what the new electronic ones do for local and regional trails (I think they would print okay, they just aren't distributed directly on paper).
- detailed maps from 1:10,000 to 1:1,000,000
- hiking routes which are actively maintained. You can create your own hiking routes, and it will estimate the time that it will take to complete them.
- historical data, like historical maps since 1864 and aerial photos
- aeronautical maps, naval charts, geological maps, ...
- basically any kind of data that you can find on maps, such as land registery, water planning, spatial planning, etc.
I am not sure if other countries provide this level of service free of charge. I would be curious to see what other countries offer on this topic.
