Hello fellow Aussie!!
I am using the First Response ones. I tried Forelife but I found them really hard to read (as there is often a 2nd line which is lighter than the test line). First response you wee into a cup (I prefer this than trying to get it on the stick) then dip the stick in for 10 seconds. They are really clear, and I used them last time when I got pregnant with my daughter. You can get a 7 day pregnancy planning kit which includes 7 OPK tests and 1 pregnancy test. Priceline sell them.
Good luck!!!
