A winning bet returns a payout that is based on the odds quoted by the bookmaker. Betting odds can be displayed in various formats. Australia uses the decimal odds system, which is arguably the most intuitive format. You will sometimes see decimal odds referred to as European odds due to their popularity in Europe, or occasionally as International odds. Many bookmakers offer numerous odds formats on their website, however most Australian bookmakers offer only decimal odds. Below is a comparison of the most popular odds systems. The equivalent odds are provided for the following examples:

Example 1 represents a bet that provides a 150% total return. A winning $10 bet would return $15 for a $5 profit.
Example 2 represents a bet that provides a 300% total return. A winning $10 bet would return $30 for a $20 profit.
