Although Australia's biggest companies – found in the S&P/ASX 200 (ASX: XJO) (^AXJO) – continue to push to new highs, there's a number of great blue-chip Aussie businesses which are likely to trend even higher in coming years. The first of which is Macquarie Group Ltd ( ASX: MQG ). Macquarie is Australia's leading investment bank with expertise in stock markets, the resources sector, currencies and financing. It is led by experienced management and continues to build its reputation worldwide. Aided by growing confidence in global markets, in its 2014 results the bank announced a 49% growth in profit and 22% increase in operating income. Global sales accounted for 68% of income with North American markets leading the charge. In the coming year, management has forecast mildly positive earnings growth and is expected to pay a 5% dividend. After missing an earnings guidance and being hammered by the media, Coca-Cola Amatil Ltd ( ASX: CCL ) moved into the buy zone.
