From Goldman Sachs’ Tim Toohey, head of macroeconomic research in Australia and New Zealand. Bolding is mine:

Although we have consistently highlighted these same themes over the past 2 years it is important to note that the challenges from these 3 themes remain mainly ahead of Australia rather than behind it:

  1. The triple threat of an income shock via commodity prices
  2. An investment shock via the mining sector
  3. And a fiscal shock via federal and state governments

are the threats that present as the key domestic risks for 2015.

1. The income shock via commodity prices is now mostly behind Australia

  • Iron ore prices are currently below our spot forecasts
  • Key commodity prices may not fall too much further … (but) the impact of these declines in spot prices on the terms of trade will still be apparent over the next 9 months and impact upon household income growth noticeable for another 12-18 months, if historical relationships again prove accurate
  • A weakening in nominal GDP growth will become increasingly apparent as Australia enters 2015, presenting downside to inflation and wage outcomes

2. The investment shock from declining mining investment is only approximately 1/5th of the way through:

  • The long expected LNG-supply led boost to activity is still ahead
  • But there has been some further slippage in the timing of the production ramp-up into 2016 and the transition from falling investment to full production is likely to be a bumpy process
  • We estimate that mining investment will subtract 150ppts from real economic growth in 2015 and 100ppts in 2016

3. The fiscal shock has only recently commenced

  • From 1 July 2014, the combination of a deficit levy tax, an increase in the Medicare levy, an increase in the superannuation levy and more recently the re-indexation of petrol excise was phase 1 of the fiscal tightening
  • Restrictions to welfare entitlements and proposed co-payments for medical visits remain key elements of the May Budget still yet to pass
  • Further budgetary reform will be required in the May Budget
  • The declines in commodity prices set to strip over A$25bn from government revenue over the next 4 years
  • Lackluster nature of the non-mining economic recovery constraining income tax revenue
  • Government will likely need to raise A$30bn in new taxes or via expenditure cuts over the Budget horizon should it wish to continue to meet its existing objective of returning the Budget to surplus by 2018-19
  • We estimate that the fiscal drag will take 0.6% off real economic growth in 2015 and 0.4% off real economic growth in 2016

More:

  • the growth impetus from the new housing recovery is set to slow
  • although housing approvals may remain at a high level in the coming year the contribution to economic growth will progressively diminish. Given this has been the primary source of new non-mining economic growth in 2014, home building will prove less of catalyst during 2015
  • Financial conditions can no longer be classified as ‘loose’
  • The RBA definition of financial conditions has narrowed during 2014 to focus on lending rates faced by business and consumers. Our definition is a broader concept that encompasses the currency, short term and long term interest rates, corporate bond spreads, asset prices and commodity prices. While it is commodity prices that have provided most of tightening in financial conditions in 2014 our measure of financial conditions excluding commodity prices also suggests that financial conditions have moved from ‘easy’ to ‘neutral’. Thus into the most acute phase of the economic impact of these 3 key economic shocks in 2015 the 2 primary forces that have provided the impetus to economic growth in 2014 are fading.
