I also live in WA. I suggest going to Rottnest, maybe you could go down South too and visit the chocolate factory and fudge factory and go to the Candy Cow at Coworemup ( don't know how to spell that place sorry!!) YOU HAVE TO TAKE THE STUDENT TO THE FOOTBALL, try for a Derby if they are here then because they have the BEST ATMOSPHERE but any match is good. Personally I would go see Freo but that is just coz I LOVE them.
If she/he is coming later in the year you can go to Adventure World, Im not sure when it opens up again. Go to Kings Park for a picnic, go shopping in the city, go to the zoo too of course. There is also a wildlife park somewhere, I think it is called Cahona Wildlife Park ( again Im not sure of the spelling ) any way at this park you get to hold koala's. You can go down to the foreshore see the bell tower and catch a ferry?? Fish and Chips in Freo at Ciccerello's is also good and you can go on speed boat rides from the jetty there.
Hope some of these suggestions are good. Have fun
