I understand what you guys are saying, but like it was said in the first post it is a business, and they arnt going to give their money away. If they get $200 000 on a horse, in fixed odds compared to say $100 they are going to drop the price, if they didnt they would be stupid.

Also i wasnt aware you were comparing a the TAB fixed odds to centre bet or something similar. There would also be a good reason for them having better odds about the Australian horses. The only people that have the accounts with the other bookmakers are obviously serious punters (well more than a weekend punter) and are therefore more switched on with horses around the world. So you will get alot of ppl simply backing the Australian horses with the TAB on what they have seen here in Australia and thinking nothing can beat them, whereas the "more informed" punter will know the quality of the horses they are against and you will get more money being bet on the non-Australian horses in the race, and therefore the companies can afford to offer a better price on the Australian horses.

I hope that makes sense to anyone reading it, it did for me anyway :P
