Federal Labor banked almost $600,000 from gambling companies last year from its pay-for-access subscription packages for companies and executives, which fly under the radar because they are not technically donations.

Payments from Sportsbet, Tabcorp and pubs and pokies giant Endeavour Group along with ClubsNSW appeared to be part of at least $5 million that flowed into the party’s coffers from the Federal Labor Business Forum, according to analysis of Australian Electoral Commission data.
