Likely, the current is low. Most "neons" pass only low tens of
milliamps, max. If that's the case, most any small power transformer
rated for 6-10VA with a center-tapped 220V primary would do.

Use it in "autoformer" mode, hooking 220V to the outside leads, and
tapping 110V from the line-neutral leg to the center leg.


Ok, just to make sure bases are covered, I've been told that in
Australia, 220 is -220-, either leg to ground is 220, not 110.
Don't know if that changes anything you wrote above...

any transformer with a 220V input and a 110 v secondary (or 115 or 120
or anything reasonably close) will work - when you get to AU just pull
apart an old something or other and repurpose the transformer, or go to
a surplus store. Though things cost more there, surplus stores still exist
