Bruxelles had a couple of very good independant wine shops, not always cheap, but with a good range. Nicolas, the French giant was a massive disappointment, a dull & bland shop with too many unimaginative wines by massive producers.
There's a really useful utility available called Wine-searcher, that many of us use to track down specific wines. However it also lists all the merchants who are registered with them. This will be a decent start point for some internet searches of decent merchants. Attached is a link to the Belgium merchants listed:

As for wines, you should be able to get very good french wines at those prices. I'm not quite sure of your prefences, but for starters I'd suggest
Gigondas by Santa Duc - available in Bruxelles at €16+ local sales tax. Big but stylish wine from Southern Rhone.
Searching for AUSTRALIA SHIRAZ brings back a short list, which suggests there's not much Aussie wine in Belgium. Producers such as Hollick, Grant Burge, Wirra Wirra, Capel Vale,Mitchelton, Cape Mentelle have wines there. One merchant in Antwerpen listed Grant Burge Filsell Old Vine 2002 at just over €17+ local tax, which might be a good starting point.
So I'd echo the sentiments of scouting out a local merchant that looks to be passionate about what they do (i.e. not a supermarket or Nicolas!) and ask them to suggest a good couple of wines (give them whatever advice you can to help e.g. I think I prefer fruity/savoury styles; I like Bordeaux(Cabernet)/ Rhone(Shiraz) / Alsace(Riesling) styles; etc.
Go back to them after you've tried the wines & (whether you liked them or not) say whta you thought, what you liked & hwat you didn't and that will allow the merchant to suggest different wines. If they run wine tastings, then sign up for them, as it's the cheapest way to form judgements.
Hope this is useful & that you find lots of good wines.

p.s. I'd just like to declare that Pierre Marcolini chocolates of Bruxelles are the best in the world - absolutely stunning.
