Victorian smoking bans took another chunk out of Tattersall's turnover in the latest financial year, but the pokie and lottery machine giant said the worst was over as it prepares for a $2 billion public listing. Financial accounts tabled through the Victorian Parliament for the year to June 30 show turnover for Tattersall's Holdings slipped to $12.9 billion from $13.3 billion. But the axing of nearly 50 staff and better technology efficiencies combined to keep costs low and helped Tatts to a net profit of $70.7 million, up from $60.9 million a year earlier. The holding company also paid a $111 million licence fee back to its parent entity, the Estate of the Late George Adams.
