Having spent many a happy hour in a Jabiru, I can confirm that it can be a little challenging in crosswinds. The reason for this is that it has too little rudder area, though this was addressed on later models.
If I remember correctly, it could run out of rudder in a crabbed approach/kick straight scenario. The highest crosswind I ever landed in was about 25 knots at Le Touquet. Because they have a very long runway I was able to minimise the crosswind component by landing at 70 kt, no flap and one wheel at a time. It was a case of flying it on and holding it down. There's no way the crab technique would have been successful in that wind.
I suggest that when the wind is right you get your instructor to demo a few landings while you sit back and take it all in. Sometimes a just watching someone do something well will improve the way you it. God knows I'm better at snooker after I've watched the world champs for a few hours.
