Decided to use Coopers Wheat beer kit + Wheat DME, and add a little Hallertauer (classic Bavarian weissbier hops) both for aroma and bitter (10 and 60 min). Since the kit already has some hops, I'll just use a tiny bit (10-20g in ~10-15 liters wort =~3 AAU) to be on the safe side, yet be able to try boiling and adding hops. No dry hopping.
Make sure to do a clean racking to bottling bucket, so there's only some yeast in the bottle, like a real hefeweizen.
Made with 500g LDME and 300g Dextrose, (like package suggests) 150g malted wheat steeped for 20min, and 10g Saaz dry in the fermentor from day 4 til day 10. Used the kit yeast at 19-21'C. Turned out quite well after 3 weeks with a very pale body and a nicely white, fluffy head. The body isn't overly light, and the taste is delicate and well balanced with a nice impart from the Saaz. Perfect for hot summer days. Only other comment is that it would benefit from a proper wheat yeast such as WB-06. I'd give this a no-joking 5-star rating.
Another user used wyeast 3068 (for real German tasting weissen, not American hefeweize)

Coopers site suggests using kit + 1 kg of Coopers Wheat malt and WB-06 / Munich yeast; to make 'Hefeweizen'.

For those interested: poster Les posted this from another board from Down Under. It's close enough that I'm going to give this a whirl:
(6 gal batch)
~2kg Wheat Dry Extract (62.5%)
~1.1 Light Dry Extract (37.5%)
12 grams Tettnang (90') 6.4 IBU
9 g Pearle (90') 8.6 IBU
7 g Tettnang (45') 3.4 IBU
7 g Tettnang (15') 1.0 IBU
1 pkg Weihenstephan Wyeast #3068)
Beer Profile Estimated Original Gravity: 1.051 SG (1.044-1.052 SG)
Estimated Final Gravity: 1.010 SG (1.010-1.014 SG)
Estimated Color: 13.6 EBC (3.9-15.8 EBC)
Bitterness: 19.3 IBU (8.0-15.0 IBU)
Estimated Alcohol by Volume: 5.3 % (4.3-5.6 %) Actual Alcohol by Volume: 5.3 %
Actual Calories: 475 cal/l
Start with ~2-1/2 gallons of water in the pot and bring to the boil. Remove from heat and add 2.2# of the DME (wheat or barley, shouldn't make a difference), and dissolve. Return to the heat to boil (watch for boilovers!) Add the remaining DME (off the heat) in the last 5 or 10 minutes of the boil.
The advantage of the DME limited quantity boil, is that you can cool in a laundry sink or bathtub of cold water.
Ferment with 30% headspace at or below 68 deg F; bottle as soon as fermentation is complete
