Ive worked in TAB'S and had regular bikers ( dont call them bikies) who would bet 5-10k on a weekend of leauge matches. $1000 on will a 40/20 be kicked? No problem. $4000.00 on a team, 1-12? Every weekend. $1000 on first try scorer into some other result? If the odds allowed it. So to me $1800K on a game barely raises an eyebrow except to say that bets of, or multiple bets totalling over $10,000.00 should be recorded and paperwork filled out for money laundering / tax purposes. Which i never did.
