Hi, as Australia is a multicultural nation we can always find people to practise with. Also we can do short courses. I suggest you contact you nearest International School and ask if it's possible to get a native English speaker as a tutor. If you are a tourist guide, you speak to a lot of foreigners as part of your job. Otherwise click up to Language Partners at the top of this page and email a few native speakers.

actually, speaking with foreigner (native speaker) is one of the best and effective way of learning other languages. as you interact or speak with them, you'll clearly understand how their language are spoken and probably learn more vocabularies, and you can actually gauge your ability.... speaking ability. As to your problem to speaking with native speakers as seldom found in your country, try to make friends online instead and perhaps, do voice chatting. It'll surely helps. (just to share, I'm learning chinese too and I find it hard to find a chinese friend here because most of them speak cantonese and other chinese language other than mandarin). :)
