Rural Australia is a unique environment. 95% of what it takes to have a really good experience is down to your attitude. We will need you to be energetic, enthusiastic and engaged in every situation. Give everything a try and learn how to do it well.
You have to be aware that it is not an easy environment. It can be tough, hot, dry and dusty. The employers are fair people but they will expect you to work hard. You will be going to a real job for a real pay, this is not a package holiday.
So expect a fair bit of culture shock at first, but with commitment you will have an amazing experience.
