I had en enquiry about one of my betting accounts today with the NSW TAB in regards to a free bet i had where they paid me $3 for one of black caviars runs when it was paying $1.30 so i hedged it on betfair for profit of $70 with the understanding the extra $90 they paid me had to be turned over before i could withdraw the funds, fine i accepted that.

I had in the account a bit over $500 and wanted to take most of it out as i don't use the account that much i was told the whole amount had to be turned over before i could with draw those funds and only what i had turned over was available for withdrawal.

I advise anyone not to place to much money in the TAB account as you need to turn it over to get it out.

This may be the same for bookies, i have not noticed this before so i am not sure if it has been around awhile or not.
