I'm assuming by 'Key initiatives' you mean Budgetary Policies? If so, look up the budget overviews for the past two years and group various policies into whichever suits each E goal specifically (although many of them cross over, there are a few which are distinct to each goal)

This can help lower NFD which in turn assists in achieving the goal of External Stability (the explanation was a bit bare I know, but you get the idea).
Low Income Tax Offset? It's a rebate to low income earners where on 1 it provides individuals earning less than $30,000 with a tax rebate of $1,500. The full offset is reduced by 4c for every dollar of taxable income above $30,000, meaning incomes greater than $67,500 do not receive any benefit. Therefore it is essentially an increase in the tax free threshold, however I don't really know about the bringing foward up to $300.
^^ N.B. due to the induction of the Carbon Tax next year and the subsequent compensation package, there will be a significant reduction in the LITO provided to low income earners since the tax free threshold will be increased to $18,200
