Firstly, as discussed above, concentrate on your school studies and try to get the highest marks possible.
This will stand you in good stead for both if you do, and if you don't end up flying for your career.
Secondly, CASA have been trying to crack down on marginal colourblindness. They've even been threatening to REVOKE class 1 medicals from experienced airline pilots who have flown safely for years. It sounds like you have a fairly serious case of it. They don't actually have a safety case for it, but that's another discussion for another time.
My best advice on that front is to google and then contact Dr Arthur Pape, he's a specialist in aviation colourblindness and designed the alternate testing years ago - which many pilots have relied on to get their class 1.
Call him to discuss the tests you did and he should be able to give you a fairly quick idea of whether you are likely to obtain a class 1.
Don't start commercial flying training on the presumption that CASA might review the rules positively. They're still well and truly stuck in the 1930's and any such advancements of the science from CASA or relaxing of the standard is very unlikely.
Perhaps once you get a good job in another industry you might be able to look at recreational flying, gliding or something to satisfy the urge.
Good luck.
