My problem now is that now I am here I don't know what to do! I am staying in youth hostels and am VERY aware of the fact that my money is limited and only going to support me for a while, I feel like I need to know where my support is coming from rather than just knowing it will come.

Now that I am here I am worrying about how I am going to stay, my visa is only for a year.

Don't focus on this.

My quality of life is so much better out here; my skin is clearing up with the sun, I can eat very healthily, I get a lot of exercise. So just being here has helped with many of my problems

Focus on this.

I guess my question is how can I Know for certain that I can achieve all that I desire and be supported along the way/ be able to support myself along the way?

Just decide to believe that you will be supported because you always will be, and you always have been, since the day that you were born.

Do you worry about breathing all day long, especially when you are sleeping?

Do you wonder if your heart will keep pumping blood?

Do you have doubts that when you get into drive a car or ride a bike that you will forget how to do it?

You don't worry about any of these every day and every moment things because you just know for a fact that everything will work out fine. Use that example of knowing when it comes to your everyday life desires.

There really is no technical and detailed answer to your question. You just have to get into a state of belief that you know without a shadow of a doubt that you are on the right path.

If you do or think about things that make you feel good most of the time like maybe, "My quality of life is so much better out here; my skin is clearing up with the sun, I can eat very healthily, I get a lot of exercise. So just being here... makes me feel great."

Worrying about the unknown only produces more things to worry about.

No matter what the situation in front of you is in every moment, let life unfold for you, instead of trying to fold things into places they don't fit by being in your own personal state of bliss and joy. Vibration first...everything else second.

Focus on your ideal life in Australia every single moment that you can. No matter where you are or if someone is screaming in your face. You get to choose how you feel at all times no matter what.

Circumstances don't matter anyway. Only your vibrational state of being matters (or produces solid in your face physical matter that you prefer.)

Allow the things that make you feel good produce the physical circumstances that you desire, instead of resisting your true core vibration by letting physical circumstances produce your vibration.

The life that you want exists right this very moment...literally...Literally.

Everything exists in the Now moment. Feeling good matches the frequency of your ideal life in Australia that literally exists right now in parallel earths. You will shift to those parallel earth frequencies the more you do things that make you feel good. Worrying will simply shift you to parallel earths where you continue to worry things won't work out.

Seeing as I have no ties and obligations, I can do anything and be anywhere.

Take the last part of that sentence and milk it all day long. Repeat it when you feel really good and say it so much that it makes you giddy with joy. Sing it, dance to it, write it down, and spell it in your alphabet soup. I know for a fact that it is true, but do you?

I just need to be able to know that I can actually do that and do it in the most streamlined way as possible

You can. The most streamlined way possible is to make feeling good the most important thing in your life. Do that, and all the other puzzle pieces will gently and easily fall into place.

I was fixing a few errors in my answer and thought I would post this video I came across recently that might be helpful for you:)
