I'm Australian and white and 29.

I've dated a few Asian girls in my time and it's been some of the best experiences of my life. I was exposed to culture, food and tradition I would never have had a chance to experience otherwise. At 14 this probably isn't as important to you now, but in 10 years you'll probably feel extremely lucky to have this experience and laugh as your white mates finally discover okonomiyaki.

I've been lucky in that my family has always been very accepting. early on I suppose they might have been shocked, but honestly with the diversity in Australia, there is a high chance you'd fall for a non-white girl anyways, especially in your age group where there are many Asian/Indian/etc Australian girls who grew up here.

You're 14 and you probably won't marry this girl, so just enjoy the experience and take as much out of it as you can. On the off chance you do end up with her forever, you'll have a beautiful Japanese wife with diverse genes to ensure the kids don't end up with boganism like the rest of your family :).
