Yes you can use IRESS with both Invast and FP Markets, and they give it to you for free too when you do over a certain amount (forget what it is at the moment.)
I think you will find that with being able to do your own order routing you can do a lot more trades as there are more opportunities. Im a day trader and primarily make most my money being able to get in on ASX and out on Chi-x or vica versa.
They charge a flat percentage. Usually new clients are at 5 basis points. which is 0.05%, meaning if you do a trade worth $1000 your paying brokerage of only $0.50, thats right 50cents. You got a big learning curve ahead of you, but just making the change from commsec to other brokers will save you $100s a month in brokerage alone, let alone being able to make better trades.
Good luck!
