Sydney is Australia's biggest market and its most expensive one to win. Your marketing needs to earn its place in it.

Greater Sydney's population passed 5.5 million in 2025, and the city added roughly 75,000 residents in the 2024/25 financial year alone. The City of Sydney's Gross Regional Product reached $170.6 billion in 2024/25, with 683,472 jobs located within the local government area: a concentration of economic activity unmatched by any other Australian city.

New South Wales added over 20,000 net new businesses in 2024/25, the largest absolute increase of any state, and Sydney's financial and professional services sector anchors that growth: the sector contributes roughly 9% of national GDP and is larger in scale than the equivalent sectors in Hong Kong or Singapore. NSW is also Australia's biggest online retail market, accounting for roughly one in three dollars of national ecommerce spend. Scale like that means more prospects, and far more competitors chasing them.
