'Trades' doesn't really have any impact on a company like this. 1 client can onboard and deposit A$20k and then on a leveraged fx account trade close to A$2mln at a time (100 times leverage). All those trades are internal, so no impact or use for ISX except for the initial account opening and deposit.
So, while A$25Bln pa sounds like an enormous figure, it really doesn't mean anything at all unfortunately.
