Tabcorp will face new 'dirty money' charges with the federal government's anti-money laundering regulator raising fresh claims against the wagering giant.

The Australian Transaction Reports and Analysis Centre (Austrac) and Tabcorp were due to face the Federal Court in September after claims the betting company had failed to tell the regulator that more than 30 TAB accounts were opened under false names and used to filter fraudulent credit card funds for organised crime figures.

That court hearing has now been delayed until June 6, 2017. Austrac is expected to file additional examples of Tabcorp flouting the rules in the next few weeks with the later hearing date giving both sides an additional nine months to prepare their cases.
