Perth? Where's that? ^_^ Traveling is fun, but weary- Don't worry about it, PancaKe. While traveling alone can be scary, it's a good kind of scary. Nothing is more enpowering that going off by yourself.
Pretend you're on a mighty quest, that's what I do. (I read to many adventure novels).
As for traveling alone, will you be driving? Or taking a Bus? Either way, you're alot safer than people make out. If you're worried about pickpockets or anything, I reconmend a fanny pack. Or traveler checks!
Those are dead useful.
You should so go :3 By yourself traveling is the greatest traveling in the world. Bring a good book if you have too.
