Unsure about which group your refering to, but if it's the main organised crime syndicate the calabrian Ndrangheta then they can't even help themselves let alone helping or sponsoring someone now.
With their main office being in Calabria Italy, They've existed in Aust. since the 1920's and are a part of a global network and it was this Ndrangheta who were pulling the strings of the Australian outlaw motorcycle gangs. Since the AFP operation 383 of them have been arrested and currently another 5000 more of these gang members are investigated with the operation resulting with a further 42 of them already pleading guilty.
So while they are seeking all the help that they can get from their Lawyers now, i doubt that they'll be interested in helping or sponsoring someone for their favourite team.
