The Australian Media and Communications Agency (AMCA) has found that some of the top betting sites in Australia have breached in-play betting rules.

The controllers of Ladbrokes, Neds, bet365, and Sportsbet have all been found guilty of non-compliance with interactive gambling rules.

All three betting companies use Fast/Quick codes, which should be solely used for phone betting for the entire staking process.

In Australia, gamblers cannot place a bet during an event unless this is conducted and placed via a phone call.

The AMCA found that bettors were using the web-based applications of all of these operators, to place bets and then calling to confirm the in-play wager.
