This took several days, but I finally managed to update the Australia pages on the World of Waterfalls with GoogleMaps.
Now, you should be able to see where each waterfall is in the country, while the tier 2 and tier 3 pages have larger regional maps to help you get a feel for where the waterfalls are concentrated.
Next up on my GoogleMaps to-do list are Iceland and Norway. But since there's another couple hundred waterfalls for those self-driving destinations, it's probably going to be several more days before you'll see another announcement from me regarding their completion. Still, for fans of this site, hopefully it's something to look forward to.
