The fate of the Aussie dollar will also play a big part in boosting economic growth. If it trends in the low US$0.60 range, it should help the services sector. Last year this sector made its largest contribution to the Australian economy since 2001 and this year shouldn’t be any different, provided the dollar weakens further. Despite this, there’s still scope for improvement, primarily if the service sector’s investment could rise to match its contribution to GDP, boosting it to another level and potentially helping to offset slowing mining investment.
