Best way to make up minimal elite miles

[AnotherWorld]

I am flying to Penang this year, and doing a multi stop north american trip in March. I live in Perth. My qualifying period ends Dec 31. I will be 430 elite miles short of silver for 2015. How could I make up this tiny shortfall in the most efficient way possible??
