CAAi - FCL
The Australia sat exams finish by UK CAAi after the sitting in March.
If you're exempt and hand in the application as per their deadlines, whichever they are, you could do your best in February or March.
After that, you'd be still able to go to closer Kuala Lumpur (done at British council on behalf of). Sure, there's a premium payable on top of about 120AUD per exam or so for CAAi locations, but if you're up for it..
Any waivers of/exceptions to compulsory 'ground school' ie revision/brush up classes on top of distance study, as mentioned, would need to be approved/checked with the CAA of relevant country.
