pazurita,
If you failed to meet your deportation order I HIGHLY encourage you to immediately hire a registered migration agent, or an immigration attorney. This can be a very complex issue, and not suitable for discussion on a board such as this. It is in your best interest to get some professional advice because of time limits and mitigating circumstance can play both in your favour and against it. It also may have an adverse affect your ability to return to Australia.
