Websites Blocked
ACMA reported on 15 July 2026 that 1,774 illegal gambling and affiliate websites had been blocked since the Australian website-blocking program began in November 2019.

RTP — Return to Player is a theoretical percentage calculated across a very large number of game rounds. It describes the long-run mathematical return built into a game rather than the amount one individual player should expect back from one session.
The key word is “theoretical”
Short sessions can finish far above or below the published RTP because random outcomes vary. RTP is useful for understanding game mathematics, not predicting the next spin.
Volatility describes the distribution and size of outcomes. A lower-volatility game may produce smaller outcomes more frequently, while a higher-volatility game may produce wider short-term swings.
RTP and volatility describe different parts of the game's mathematical profile. Looking at either number on its own gives an incomplete picture.
Describes the theoretical return built into the game across a very large sample of rounds.
Describes how smooth or uneven results may feel across shorter periods.
What neither number tells you
Neither RTP nor volatility tells you which spin will win, when a feature will appear, or whether a session will finish ahead.
No. RTP describes theoretical long-run performance across a very large number of rounds.
Previous random outcomes do not create an obligation for a future round to produce a win.
Increasing the stake increases the amount of money at risk. It does not reverse earlier losses.
Not necessarily. RTP and volatility are separate characteristics.
A useful limit is decided before gambling begins, not while reacting to wins and losses. The amount should be money you can afford to lose without affecting bills, debt repayments, savings or essential expenses.
A useful warning sign
If stopping at a preset spending or time limit feels difficult, that is a reason to stop and seek support rather than increasing the limit.

It describes a theoretical long-run average return across a very large number of game rounds. It does not mean an individual player receives $96 back every time $100 is spent.
No. A higher theoretical RTP changes the long-run mathematical expectation, but short-term outcomes can still vary significantly.
Not necessarily. Volatility describes the distribution and size of swings, while RTP describes theoretical long-run return.
