Hi Rezz, thats great!!! to answer some of your questions...
http://www.askted.com.au ----> this is Perth based web site tells you What's happening around the Perth, you might find some functions you guys can visit.
or Please visit to Japanese cultural centre @ Level 25 QV1 building, 250 st george's tce Perth its CBD. I work on same floor... I would come out and say HI!!! building looks like this they will give you best information about Perth in Japanese and english....
Club? have to take them to burswood international resort (aka casino) RUBY ROOM and North Bridge the club district... Perhaps WA museume and Art gallery.
if you have car then definately Penguine Island approx an hour south of Perth or even magater river... polly have to 2day trip. (beautiful winery there) I dotn think many asian ppl will see view like that...
also maybe if they have enough energy the ZOO!!! cant go wrong there... at the moment it would be better go early in the morning when they just opened cuz animals most active dawn and dusk.
its big place so you needs careful planning.!!! I am sure eveyone will have fun!!! if you have any questions Just PM away
