This must be about the only thing going on in this vast area of rural Australia, but it's pretty impressive. The markets take up essentially all the available space in the center of this town, with one sprawling hill, a separate enclosed space, and a few more food vendors up above in the other direction. It took me a while to work through the whole thing, and I don't know that I've ever seen a bigger market of this type.
There are a lot of diverse vendors; plenty of clothing and objects d'art, but no shortage of food either. I was quite happy with the food I found, including the best Nepali dumplings I've had in this country (or maybe anywhere), some sweet fresh ginger beer, delicious curry spring rolls, and a Malaysian roti. If I had a larger stomach, there were plenty of other options. The clothing of course is expensive and I didn't see much that excited me, but food-wise, I think anyone could do well here.
Given the location, I would not (and I did not) travel up from Brisbane primarily for these markets. They aren't that good. Coming from Noosa or Sunshine Coast on a lark might be worthwhile, but I wouldn't call it mandatory. What is nice though, is that if one is traveling to Noosa (or from, for that matter), you'll pass through this area, and it makes for a great stop along the way. As the website notes, there is a train stop in Eumundi, but the train doesn't go this far north often enough to be of any use to a market-goer. The buses, however, work fine if you have some time on your hands. I was quite happy to take a break here after a long train ride, and I'd go again.
