Simply put - No. An EEA2 application can only be lodged in-country.
By the way, I do not think that your Tier 1 visa will be valid if you are away from the UK for a year. May be wrong...
You can either apply for a EEA Family permit (entry clearance) from BHC in OZ or enter the UK holding only your passport and marriage certificate as you are a non-visa national.
Once you both enter the UK and your husband begins exercising a treaty right - employment, self-employment, studying, self-sufficient - you may apply to the UKBA for a residence card (using form EEA2) confirming your rights of residence in the UK as the spouse of a qualified EU national.
Bear in mind that if your husband is exercising treaty rights as a student or self-sufficient person then your EEA2 application would need to be accompanied by comprehensive sickness insurance which, from the UKBA's stand point is not NHS cover. This means that you may have to go the way of private medical insurance to satisfy this requirement.

After 5 years of continuous residence in the UK (under the EU route) you will automatically acquire permanent residence.
If your goal is to acquire permanent residence/British Citizenship in the future then bear in mind that time spent under the UK settlement route and EU route cannot be intertwined. By this I mean: say for instance you
can remain in the UK on Tier 1 but later decide to switch to the EU route (by applying for a residence card as a non-EEA spouse), your residence clock will be reset to zero and any time spent under Tier 1 lost.
