The total Australian gambling market is projected at US$15.88 billion in revenue for 2025, according to Statista, with a compound annual growth rate of 2.09 per cent through 2029. The global online gambling market hit USD 78.66 billion in 2024 and is projected to reach USD 153.57 billion by 2030. Australia sits at the intersection of these trajectories — a mature gambling market with world-leading per-capita expenditure that is rapidly shifting online, driven partly by payment innovations like PayID.
More than 27 million PayID registrations exist in a country of 26 million people. That penetration rate means the payment infrastructure is effectively universal, and the crossover into online gambling has been one of the fastest payment-method adoption curves I have observed in any market.
What Is Driving Online Gambling Growth in Australia
Three factors converge. Mobile penetration is the first — Australia has one of the highest smartphone adoption rates globally, and the shift from desktop to mobile gambling has been decisive. Online wagering turnover surged by 165.7 per cent year on year to AU$75.4 billion, with the majority of that growth driven by mobile sessions.
Payment innovation is the second factor, and PayID sits at the centre. The NPP processes over 155 million real-time transactions monthly, and PayID’s integration into casino deposit flows has removed one of the last friction points in the player journey. Before PayID, a player who wanted to fund a casino account needed to either use a card (with its associated delays, blocks, and fee exposure), set up an e-wallet (adding a middleman and pre-loading requirement), or wait for a traditional bank transfer (one to three business days). PayID collapsed that process to seconds — and the adoption numbers reflect it.
The third factor is the supply of operators. Both licensed Australian wagering services and offshore casinos have expanded their PayID integration. ACMA has blocked 1,708 illegal gambling sites, but new operators continue to enter the market. The combination of strong demand (high gambling participation), frictionless payments (PayID), and expanding supply (more operators) creates a growth environment that regulation is working to moderate but has not reversed.
How Regulatory Changes Shape the Growth Trajectory
The credit card gambling ban, effective 11 June 2024 with penalties up to AU$234,750, removed one payment channel but inadvertently accelerated PayID adoption. Players who previously deposited with credit cards needed an alternative — and PayID, already embedded in their banking apps, was the most convenient substitute. The ban reduced gambling with borrowed money but increased the volume flowing through instant bank transfers.
The 2027 gambling advertising ban will reduce operator visibility in broadcast media, potentially slowing the acquisition of new players. Whether this reduces overall market growth or simply shifts marketing spend to digital channels remains to be seen. The advertising reforms are the most significant demand-side intervention the government has announced, and their impact on market size will not be measurable until well into 2028.
BetStop’s 59,830 registrations represent a small but meaningful segment of the gambling population opting out. As self-exclusion registers become more effective and gambling blocks at the banking level become more common, the addressable market may plateau — though the historical pattern suggests that technological convenience (mobile, instant payments) continues to outpace regulatory friction.
For PayID casino players, the practical implication of market growth is more choice. More operators competing for Australian deposits means better bonus structures, faster withdrawal processing, and broader game catalogues. The risk is that growth also attracts lower-quality and fraudulent operators. The scam prevention guide covers how to distinguish legitimate operators from opportunistic entries.
