Wow, great responses everyone - much appreciated.
>Before this discussion goes off on a tangent, which version of CC-by are
they currently using?
You can see this for instance at:

Thanks for confirming that. I was a bit confused by the term in the CC-BY
>You may not apply legal terms or technological measures
<http://creativecommons.org/licenses/by/3.0/au/#> that legally restrict
others from doing anything the license permits.
Which could be interpreted to mean you can't apply CC-BY-SA which
"restricts others" from using the data and not sharing it, which "the
license" (CC-BY) "permits". But CC's wiki explicitly says this is ok:
>When creating an adaptation of material under the license identified in
the lefthand column [BY], you may license your contributions to the
adaptation under one of the licenses indicated on the top row [BY-SA] if
the corresponding box is green [it is].
>Where "etc." means "TomTom". There are only four worldwide geodata providers.
It's hardly a slippery slope of individual permissions.
Good point. Although hypothetically there could be non-worldwide providers.
>So a simpler route here would be to suggest "upgrading" to use CC-By 4.0?
Getting DELWP (and most likely the rest of the Victorian government) to
switch to CC-BY 4.0, let alone CC-0, would be a huge task that would
probably involve all kinds of bureaucracy, working groups, etc etc.

>Perhaps helpfully, there is a New Zealand Government precedent for the
situation you're facing here. Land Information New Zealand licenses a wide
range of geospatial data under CC-BY licences. However, it has also allowed
data to be made available on OSM under the ODbL. See here for details:
>I suggest you draw the Victorian State Government's attention to the
approach taken by Land Information in New Zealand, with a view to asking
the Victorian State Government to take the same approach. I completely
understand their position of not wanting to "get into creating one-off
variations for every potential user with a preference" but I think it's
important to appreciate that we're talking here about a global project
which has decided on the ODbL, that it would be extremely difficult to
change the current regime to another one and that there is no real downside
to the Victorian State Government dual-licensing its data, once under CC-BY
and separately under the ODbL (or, actually, allowing OSMF to license under
the ODbL). It's perfectly entitled to do that and people who want to use
the data directly from the Victorian State Government's site under CC-BY
can always do so. Most significantly, dual-licensing under CC-BY (via a
government site) and the ODbL (via OSM) allows the data to be used in a
wider range of contexts and for it to be mashed up with other rich datasets
already in OSM or that may be added to OSM in the future. Allowing this
could result in cultural, environmental, economic or social benefits for
Australians. This is all entirely consistent with the rationale for open
licensing in the first place.
Wow. Hard to believe that New Zealand open licensed their data 7 years ago.
Maybe this will be the precedent we need. That's really an excellent,
well-worded summary. Would it be alright with you if I CC'ed you in my next
response to them (which they have asked to be directed to *their* legal
