They always make it sound like it's the consumer pumping the money in, but in reality those figures are mostly made up of business facing products & services. 

It would be a tad more than Danny's "Festival of Football" mate :)

Buying plane tickets etc. doesn't suddenly make you richer. If you didn't spend your money on that you would probably do it on something else, or invest it or whatever.

From a national perspective, the only genuine economic boost is from international tourists (plus players, officials, etc.) who came here for the WWC, and who otherwise wouldn't have come to Australia. Everything else is money that would have been in the economy anyway.

From a state perspective, it might be good for NSW if fans came from Victoria to watch a match, but then it's correspondingly bad for Victoria. And since there are matches all over the country, it's pretty much a wash.

. The money would not necessarily be in the economy. The money from a tournament from people travelling interstate goes directly to the pocket of local businesses. 

Pretty much this. I drove down to Sydney last Monday night, got on the piss, got dinner, watched the game, had more beers, late night kebab, uber and stayed the night in accommodation. Got up in the morning and had breakfast, filled the car up and drove 500k back home.

Would not have spent a cent if I'd have stayed at home watching Have You Been Paying Attention.
